VITROLA, CERVEJA E MP3

Os freqüentadores de dez bares no Rio de Janeiro poderão escolher, a partir deste mês, a música que querem ouvir direto da internet antes de cada gole de uma boa cerveja gelada. A carioca Ponto-I, empresa incubada na Universidade Federal do Rio de Janeiro, criou a primeira jukebox baseada na tecnologia MP3. Em vez dos tradicionais CDs, o equipamento irá contar com 20 mil canções arquivadas em um computador que podem ser executadas por um preço de R$ 1 para cada sessão de jazz, rock ou MPB. Caso o usuário não encontre a canção desejada, a jukebox pode fazer uma busca na internet e ao final do dia carregar no equipamento toda a seleção da freguesia. “Os donos desses estabelecimentos também poderão definir os gêneros de música que preferem em cada vitrola”, diz André Oliveira Dias, diretor da Ponto-I. A empresa instalará até o final do ano outras 30 máquinas no Rio de Janeiro.

Se para cada idéia/invenção que eu tive e um dia alguém acabou fazendo, eu também fosse reclamar devia estar chingando muito. Fora as que eu tenho e que alguém certamente vai criar ou está criando.

Truco! Esse cara não deve estar pagando nada de direitos autorais... Se é justo pagar ou não é outra história, mas que podem apreender as máquinas, isso podem...

Não creio..é uma incubadora universitária, as coisas tendem a ser certas. A incubadora da USP soltou um totem que grava um cd com as musicas que vc escolhe por treis legal tb, armazenando em mp3, pra por em shópis.

só complementando, sobre pirataria: li um artigo esse fim de semana de um professor da Texas University at Austin - How many pirates should a software firm tolerate - que defende que a pirataria, em um certo nível, não só é tolerável como é desejável. :o Ele argumenta em cima das famosas curvas S de difusão de inovação: como as epidemias, uma tecnologia nova tende a atingir pessoa por pessoa, adequando-se a cada "organismo" - novas versões, incrementos - até que se atinja uma massa crítica de infectados/usuários, a partir da qual a velocidade de adoção acelera sensivelmente. Pois bem, o tal profesdsor argumenta que os piratas têm um papel fundamental para que se atinja a massa crítica. Obviamente há um ponto de inflexão, a partir do qual os piratas passam a verdadeiramente destruir valor econômico.E, pra terminar politicamente cvorreto, o artigo diz que medidas simples de mkt, como samples bons, acabariam com a pirataria.

Do vinil ao MP3

É hora de tirar o pó de suas bolachas negras. O velho toca-discos agora
exibe tecnologia de ponta e preços que chegam a US$ 150 mil.
POR CARLOS SAMBRANA

O vinil, o velho bolachão que rodava nas vitrolas e foi aposentado pelo CD, está de volta. Amado pelos audiófilos, loucos pelo som original, o LP virou mania – e, acreditem, promete ser um dos destaques de 2005. Ele aparece nas prateleiras das principais lojas de equipamentos musicais. Ganhou toques de modernidade e tecnologia. Explica-se: há no mercado, hoje, toca-discos que chegam a custar US$ 150 mil. “Estes aparelhos fazem com que a música soe mais natural”, diz Fernando Andreti, diretor do Clube do Áudio, agremiação de saudosistas de São Paulo. “Eles conseguem tirar os chiados da gravação.” A indústria que gira em torno do LP tem um pé no futuro, ancorada Algumas fábricas na Europa voltaram a fabricar o vinil – e para executá-lo, trataram de desenvolver a parafernália sonora. A Sony, por exemplo, produz uma vitrola high-tech, a ELP. Em vez de agulha, o que transforma as faixas musicais em som é um leitor a laser. A inglesa Vestax criou um aparelho que grava músicas de arquivos digitais MP3 em discos de vinil. A traquitana custa US$ 6,5 mil.
Trata-se, a rigor, de um movimento quase artesanal, e por isso mesmo cobiçado. Os discos, antes fabricados em massa, agora são produzidos em pequenas quantidades. Os modelos antigos, guardados em casa, viraram moeda de valor. Raridades são vendidas a peso de ouro. “Há LPs que chegam a valer US$ 30 mil”, diz Júlio César dos Santos, dono da Áudio Classic, loja paulistana especializada em discos antigos. É o caso do primeiro Bob Dylan, na edição americana, ou das primeiras gravações dos Beatles, que chegam a custar US$ 15 mil a unidade. Prepare-se, portanto, para abrir um espaço dentro de casa para os discos que hoje custam R$ 10 e poderão, no futuro, valorizar em ritmo aceleradono atual sucesso dos DJ’s, estrelas internacionais, roqueiros do século 21.

Eu não sei se a qualidade é realmente superior ou se na verdade é um certo saudosismo. Afinal, a mídia de um CD/DVD hj em dia consegue gravar todos os canais de audio sem nenhum tipo de "prejuízo". ;( ;(

Na minha leiga (mega leiga) opinião, o audio só é "diferente", não melhor ou pior - aquele "chiadinho" do vinil acho q é o q mais atrai neste tipo de mídia, não necessariamente a qualidade intrínseca do audio. :zzz: :zzz: :zzz:

ou seja, é mais um saudosismo do que estávamos acostumados a ouvir "antigamente"....

Diz a lenda que o CD não reproduz as frequências mais altas, que mesmo que inaudíveis, são sentidas por nós.
No MP3 essa perda é maior ainda, e mesmo assim, não sinto a diferença

O que eu acho legal destas soluções é poder aproveitar uma coleção já existente, sem ter que começar de novo.

Tem um pai de um colega, por exemplo, que tinha todos os Vinis dos Beatles, e depois gastou uma fortuna comprando os CDs..... E hoje eu baixo em algumas horas no emule ;)

Pessoalmente, não sendo audiófolo, prefiro ter pouco chiado na música. Mas não tem jeito. Assim como meu pai prefere, no carro dele, o Motorádio com sintonia mecânica de dial (que ele podia abrir e arrumar) a um Sony com mp3-player, quem usou muito o vinil sempre vai gostar dele.

Olha aí... Até os bandidos tem de ficar espertos com as mudanças que a tecnologia está gerando...

P2P File-Sharing Ruins Physical Piracy Business
Written by enigmax on March 17, 2007

If the likes of the MPAA, RIAA and IFPI are to be believed, file-sharing is causing worldwide havok, costing billions of dollars and creating unemployment. It’s true that some people are feeling the P2P effect; they’re called ‘physical pirates’ and one of them says that file-sharing has ruined his business.

Tony started his life of piracy sometime in the 1990’s working markets, car-boot sales and pubs in the UK, selling counterfeit PC applications/games and console discs for a fraction of the retail price. “The profit was amazing back then” he recalls “We were getting £25 ($48) for a couple of PSX games and £15 ($29) for a single CDR with the latest utilities on. We couldn’t make them fast enough.” Things were looking good for his little enterprise and before long he was clearing up to £1000 ($1,942) profit each week.

According to Tony, the first 2 hours of every Saturday and Sunday morning at the local flea market always proved the most exciting. “We’d take 60 cases of CDRs down in the van and as soon as we got there a crowd would swarm around us. We had no competition and it was obvious the punters had no other suppliers. Inside 30 minutes, 90% of the stock would be gone with some customers taking 2 or 3 cases each, presumably to sell on. After 3 hours we were cleared out and on our way home, always with huge amounts of money.”

By 2001, Tony was renting a factory unit and employing 3 people to operate duplicators 24 hours a day, 7 days a week but although business was lively right up to 2004, profits were being squeezed every year. Forced to increase the amount of media burnt each week to make up for the shortfall in profit, it became clear that the business was in trouble - demand was falling dramatically.

“In 2005 we shut down the factory unit” said Tony, “we just couldn’t keep going on that scale, nobody was buying anything in quantity anymore. So we closed up and moved back into a bedroom at home with my wife and her sister operating the burners, something they hadn’t done in years. They weren’t happy.”

Tony used to enjoy the finer things in life - a beautiful house, high performance cars, exotic foreign holidays, up-market restaurants and fine wine. I met him by chance, wearing overalls and sitting on a forklift truck, working in a factory manufacturing boxes. Sipping on a mug of tea he explained “We got to the point where we just couldn’t make ends meet anymore, I couldn’t even keep a couple of dozen burners going so that was that. I had to get a job and so did my wife. She’s gone back to hairdressing and i’ve come back to what I was doing before - warehouse work. We’ve moved to a smaller house and i’ve had to get a sensible car. Things have changed quite a lot.”

Tony is very clear about why his rags to riches story has gone back to rags again. “File-sharing, P2P - call it what you like. When you asked a customer why he wasn’t buying anything, 9 times out of 10 it was ‘BitTorrent this, LimeWire that’. Add that to the fact that huge numbers of PC users have burners and fast broadband and its obvious why I had to get out and earn a living another way. We had it good for a while but I don’t think those days are coming back.”

P2P is a very powerful machine and although Tony could see that his operation was feeling its effects, he admits that he sat back and did nothing about it and consequently, his business has paid the ultimate price. Other industries affected by P2P should take note: Don’t be a Tony. Overhaul your business model. Quickly.

An iPod Rival With an Edge
Music Player Uses Wi-Fi Connection; No Search on Device
May 2, 2007; Page D10
Since its introduction in 2001, Apple Inc.'s iPod has taken over the portable-music-player industry, gaining steam each year and rolling over competitors one after the other. Its simple interface, navigational scroll wheel and iTunes software program make it a pleasure to use -- and impossible for other companies to beat. To stay fresh, Apple regularly introduces iPods with thinner builds, lighter weights, longer battery lives, brighter screens and new functions.

But despite improvements on the original iPod, none has enabled interaction with other players or wireless Internet connectivity -- two features that competitors are eager to offer so as to chip away at iPod's huge market share. Microsoft Corp.'s Zune music player, for example, was shipped with built-in Wi-Fi, enabling song sharing -- albeit limited -- with nearby Zunes.


Apple is about to bring out its own wireless music player in the iPhone, which combines a full iPod with Wi-Fi and cellphone connectivity. But so far, it's unclear whether you'll be able to use the iPhone to download or share music.

This week, I tested San-Disk's $250 Sansa Connect player, a collaborative effort from SanDisk Corp., Yahoo Inc.'s Yahoo Music and Zing Systems Inc. that comes with built-in Wi-Fi for more than just limited sharing with other players. Unlike the iPod, which must be plugged into a computer to load new music, Sansa Connect can play and download content on the player whenever a Wi-Fi network is available, including photos, Internet Radio, songs from Yahoo's music store or recommendations from friends.

The Sansa Connect isn't without flaws. Downloading music on the go requires a subscription plan that costs $144 a year or $15 monthly, so you never outright own this content. The player also relies on a Wi-Fi connection for much of its functionality, and you may not always be within Wi-Fi range. Another problem is that Yahoo's music store doesn't sell videos and offers fewer songs than Apple's iTunes: roughly two million versus five million. Lastly, the Sansa Connect doesn't enable searching the store for specific music. Instead, you're limited to Internet radio or play-lists suggested by Yahoo, a caveat that can be maddening if you want to find a certain title or artist.

But overall, I really liked the Sansa Connect. It forced me to look at my portable player as an evolving, untethered device that introduced me to lots of songs. When it wasn't connected to Wi-Fi, I was disappointed to not be downloading new songs. My iPod suddenly seemed old-fashioned.

The four-gigabyte, black Sansa Connect isn't as handsome as the iPod, and has a stubby Wi-Fi antenna protruding from its top edge. It measures about a half an inch wider than and two and a half times as thick as the comparably priced iPod Nano, which has twice as much memory -- eight gigabytes rather than four. The Sansa Connect has a microSD card slot for expanding its capacity, but doesn't come with such a card.

The Sansa has a movable scroll wheel similar to that found on the original iPod. This wheel aids navigation tremendously, as does its smart interface. A colorful 2.2-inch display showed seven menus in a fan formation at the bottom of the screen, and I flipped through each by turning the wheel. A tiny speaker is built onto the back of the device, which came in handy more often than I anticipated.

I cut right to the chase when I opened my Sansa Connect, testing its Wi-Fi capabilities by playing an Internet radio station through the device. The player detected my Wi-Fi network, I entered my Yahoo username and password and seconds later was listening to a new Carrie Underwood song on one of 16 pop stations.

Even without a paid subscription to Yahoo Music Unlimited To Go, owners of the Sansa Connect can access about 100 Internet Radio stations; subscribers get twice as many. Each player comes with a free 30-day subscription.

You can also view uploaded digital photos without a subscription. The Sansa Connect links to Yahoo's free photo-sharing site, Flickr.com, so you can see your images as well as the top 50 photos Flickr labels as Today's Most Interesting -- but you can't view friends' albums. These photos looked good on my Sansa Connect screen, automatically adjusting to fit the screen in landscape or portrait views depending on the image.

With a subscription, the Sansa Connect's Wi-Fi connection becomes more useful. While a song is playing, you can press a button to download it or the whole album to your player. I tried this with Mat Kearney's "Nothing Left To Lose," opting first to download just that song but then deciding to get the entire album. One by one, the songs downloaded, averaging about 10 seconds each at best, until they were loaded in the player's My Music section.

Finding exact songs, artists or albums using the Sansa Connect is complete hit or miss. Rather than gaining access to Yahoo's entire store on your player, you're limited to choosing from general genres via the Internet Radio section, top songs on Yahoo Music or Yahoo's recommendations for what you'll like. So if you want to hear a certain band, you'll have to guess which category the band falls under in Internet Radio, hope to see one of its songs and then download as the song plays.

Though this lack of a search process is frustrating at times, it also might force you to discover music that you haven't yet heard. This is a different way of thinking for iPodders, so it may not catch on as easily as the Sansa player's creators hoped.

But remember: The Sansa Connect is Wi-Fi capable so it can receive software updates wirelessly, adding new features to the player at any time. Its developers say search on the device is something they're looking at for the future.

If you're desperate to load your player with familiar tunes, you can always plug it into your computer and sync it with music in your Yahoo Music Jukebox -- its version of iTunes. You can download songs with your subscription, or just buy them -- each costs 79 cents with a subscription or 99 cents without. Any regular MP3s that you have stored on your computer will transfer over to the player, as expected, which I did easily.

You can also create play-lists in your Yahoo Music Jukebox on a PC and these will be wirelessly sent to your player, ready for downloading whenever you choose. I did this with a few different playlists to get some specific songs that I wanted.

The final component of the Sansa Connect works through Yahoo Messenger. Using the player itself, you can log onto Messenger to send or receive song recommendations to or from friends who are logged onto Messenger at a PC or on another Sansa Connect player -- but they must have a subscription to listen to your recommendations, and vice versa.

Wi-Fi is a real battery sapper, and the company estimates that continuous Wi-Fi usages will cut the Sansa's estimated 12-hour battery life by half. But you'll rarely have Wi-Fi on continuously, and the player smartly shuts Wi-Fi off the instant you're not using it to conserve battery power.

Even though the Sansa Connect requires a Wi-Fi connection for most of its magic, this player is refreshingly fun to use when it works. I'm never completely surprised by the next tune that plays on my iPod and must rely on the radio or friends' suggestions to hear new music. The Sansa Connect solves that problem by giving your portable player new life.

Analógico versus digital

Postby Danilo » 13 Nov 2007, 09:33

Voltei um trecho de uma conversa antiga (que começava com É hora de tirar o pó de suas bolachas negras) pra cá, pois tem um material na disciplina PCS 2190 (a que consegui equivalência) que tem relação com o papo. Segue um trecho em azul marinho...

Em poucas palavras podemos dizer que:
DIGITAL: refere-se à representação de informações, de maneira não contínua – ou discreta- por meio de números (dígitos);
ANALÓGICO: refere-se à representação de informações, de maneira contínua, por meio de alguma grandeza física que varia de forma análoga à informação representada;

Mas afinal, qual mídia é melhor, a digital ou a analógica? Em termos de qualidade de reprodução da mídia, o que importa são características como definição, pureza, resposta de freqüência, ruídos, estabilidade, entre outras, e não o fato de o formato ser digital ou não. Um áudio digital com baixa taxa de amostragem será de qualidade inferior a um áudio analógico de alta fidelidade, enquanto que a TV digital possui imagem superior à tradicional TV analógica porque sua definição é bem melhor.


Certos entusiastas defendem a superioridade do vinil em relação às mídias digitais em geral. O principal argumento utilizado é o de que as gravações em meio digital cortam as freqüências sonoras mais altas e baixas, eliminando harmônicos, ecos e batidas graves e "naturalidade" e espacialidade do som. No entanto estas justificativas são tecnicamente infundadas, visto que a faixa dinâmica e resposta do CD supera em todos os quesitos as do vinil. E cada vez mais a qualidade média das mídias digitais em geral vão superando as das analógicos por causa dos investimentos maiores focados no digital.
