Streaming 24/96 over the Internet. Interested?

Singapore, 10th November 2011 – MP4SLS, a Singapore-based company dedicated to reshaping the delivery of digital audio entertainment, today announced the launch of a new digital audio format that allows listeners to experience high-resolution streaming audio via smartphones and tablets, without concern for delays due to buffering and other anomalies associated with limited bandwidth.

OraStream is a network adaptive streaming audio platform that provides real-time high quality audio to end users. It is based on the MPEG-4 Scalable to Lossless System (SLS) audio codec. By utilizing fine granular scalable audio in SLS and bandwidth estimation algorithms, ORASTREAM provides end users with the opportunity to consume high quality audio in real time over the Internet and mobile networks. ORASTREAM comprises two components: an adaptive streaming server and adaptive streaming client player.

I am consuming some streaming Sinatra at 24 bit/96 kHz (@ >2000 kbps according to the OraStream player) right now and he/it sounds great. Streaming music at 24/96 to the desktop over HTTP. Pinch me.

The way I understand the MP4SLS technology, OraStream streams at an adaptive bit rate depending on the network and device it's streaming to. OraStream can deliver 24/192 to the desktop and there's a Mac iOS version available for demo from the Apple App Store which streams at 16/44 due to iOS device limitations. An Android version is in the works and should be available next month as well as a Browser-based app using Javascript.

Exactly how this technology shakes out and finds its way into our hi-fi remains to be seen but I'd like to imagine that some streaming service like MOG or Spotify will license OraStream and offer access to a few million songs at 16/44 for a few bucks a month. Or maybe a live music streaming service at 24/96? Now that would be something to write home about.

I Googled for a link to the dekstop "DLP" app: http://www.orastream.com/downloads/

The main page, http://www.orastream.com/ also shows the downloads link. (As far as I could tell, mp4sls.com didn't.)

This app I found looks similar to your screenshot above, and currently runs just the demo, time-limited streaming playlist also available on the mobile apps. However, I got only 16/44 (and I have fast cable Internet) and no Sinatra. Selecting the next track instantly plays the next track, no waiting, although it did crash on me once.

In terms of the Digital Long-Playing App (DLP) and their concept of one-time purchases versus pure streaming.

I received access to a 'private' time-limited 24/96 playlist that includes Frank and Aretha. Browsing their site, it appears as if we're looking at a Beta version and bug fixes are still ongoing.

i guess it is a pretty new concept of streaming/delivering music via a DLP. Unlike the current paid models of streaming music, in doing a one-time DLP purchase, music fans get a better sense of actually owning the music.

Hi Michael - thanks for writing up.

Hi Deckeda - Michael is streaming a private demo; get in touch with me if you wish to access it but is strictly for personal demo.

I'm CEO of mp4sls, developer of the OraStream DLP. The DLP is proof of technology; for high-fidelity streaming music delivery. Because it can help artists create and distribute high-fidelity music in a playlist (any number of tracks), we termed it a digital LP or digital EP (when you play the DLP a couple of times, you will notice that like a CD it plays uninterrupted; even in the subway or elevator).

It's a new digital music concept; we think characterised in 3 dimensions:

- delivery of music direct to listeners globally (deliver the other 90% of music yet unheard);

- in high audio fidelity; up to CD quality or 24/192 KHz, if available/desired (QoS/QoE)

- linked to external resources; wikipedia, artists web-pages, social media, download stores (fan connection and interactivity). 

Thus, it can be used by artists to directly reach fans. Once an app player is installed, new tracks can be streamed to the same player; an artist can break new releases to fans. Music listeners can submit personal wav audio files to stream personal music collections in high-fidelity for listening in cars, at work; content owners can offer high-res streaming services of all those great catalogue (unplayed); Sinatra; Aretha, Miles Davies, others.  

We'll launch a web-service next for content owners to get their music into Orastream and stream-able on mobile devices and web browsers.
