BASS ASIO radio streaming choppy (1 Viewer)

[OleJ]

Problem with internet radio streaming:
When playing certain radio streams (i.e. dr.dk P3) the audio is choppy and out of sync when using ASIO.
Both files attached play fine with asio disabled using just BASS.

Attached example of a .pls that plays choppy/async and an .pls that plays fine.

Earlier (if I remember correctly) the stream would be indicated as ASIO (or digital?? What do those icons mean???) with an icon with two square dots. Now all the streams display the other icon (the two curves). Don't know if it is relevant.

Using the ASIO plugin the stream is still choppy until the BASS ASIO is disabled. (The plugin used to override this)

Edit: The best description of the phenomenon is that the sound stream is played to fast (voices sound like mice) and I guess that to stay in sync with the stream the audio is chopped up.

Tested on 2 different machines.

Hi OleJ,

I think your problem is caused by the sample frequency of the stream.
The BASS ASIO implementation uses a fixed sample frequency of 44.1 kHz.
I opened the 'choppy' stream in WMP and your stream has a sample frequency of 32 kHz.
The difference in frequencies causes the too fast playback.

About the icons in the BlueTwo skin, these indicate the playmode:
- Two seperate squares for normal mode
- Two combined squares for gapless mode
- Two waves for crossfading mode

You can toggle between playmodes with the 'G' key.

Regards,
Jan

Thanks for the explanation of the icons that really clears that up

Now concerning the streams: Shouldn't an ASIO implementation be able to handle different sample frequencies nonetheless?
Otherwise you'd be screwed real easily. Besides the problem was introduced sometime after RC2 SVN16121 so I reckon it shouldn't be there?
