BASS.NET: Switch record files from audio source

[Dev01]

I work with bass.net, and I'd like to record the audio stream of an audio source, which could come from a URL or WASAPI device, into an MP3 file. Every hour of recording, I'd like to switch recording to a new file WITHOUT losing samples. What's the best practice?

You can ensure that no data is missed during the encoder switch over by locking the stream during it. For example, you could set a timer to do this every hour:

Code Select Expand

BASS_ChannelLock(stream, true); // lock the stream
BASS_Encode_StopEx(encoder, BASS_ENCODE_STOP_ASYNC); // stop the old encoder
encoder = BASS_Encode_MP3_StartFile(stream, options, flags, filename); // start the new encoder
BASS_ChannelLock(stream, false); // unlock the stream

You can replace BASS_Encode_StopEx with BASS_Encode_Stop if you're not using the BASS_ENCODE_QUEUE flag.
