File Format for streaming only stations


Recommended Posts

Server side we simulcast in mp3 and aac. Source is usually mp3 (lame encoder) but can be aac also using a transcoder. The format of the actual audio files on the DJ machines is most often mp3 (since that's what most people have their audio files encoded with) but, can be any number of different filetypes depending on what the DJ sourcing software can handle. Most will handle numerous filetypes (i.e. mp3, aac, wav, etc.)

 

Edit: With all that said, I am still hopeful that opus becomes more popular and gets more support from players and browsers soon. But currently in html5 audio, cross-browser support seems to only be achievable by simulcasting in mp3 and ogg. Icecast is the only stream server I know of that can achieve this.

Opus should hopefully be coming into use with Altacast. I know the developer is currently testing it..... As soon as that's available I'm sure most people will use it.

 

Just curious as to which of the main media players support opus before i go ahead and stream with it.

 

Although having said that i still think AAC+ is a damn good way of streaming at 48kbps with the correct sound configuration is can sound fantastic.

Newer versions of Foobar and VLC natively support opus. Winamp does via a 3rd party plugin. LunarCaster DJ supports opus file playback (tested) and encoding for icecast (untested). I could build a fairly simple desktop internet radio player with opus support pretty easily thanks to BASS/BASS.NET having great support for the file format.

 

There's some pretty good information on opus support on Wikipedia:

I agree. The only problem right now is with browser support. I really want to move to html5 audio for web players. But, Firefox doesn't support AAC or MP3 (yet...I have read they plan to support both starting with FF 21.0...no confirmation so far though) and IE doesn't support ogg or opus. Chrome claims to support all of them, but I haven't tested that yet.

 

So if it pans out, starting with FF 21.0, I may be able to completely switch my web players over to html5. That would be cool. But, opus would still have no support from Microsoft IE or Apple Safari...go figure.
