IE,a file is mp3 another file is ogg
I want to join mp3 and ogg to a wave file,how?
I find mixer addon only can mix two file not join file!

before I can use filestream continue write,so no problem
but now use bassenc addon, I find can not do this job.
1:encode mp3 to wave(same HENCODE Return by BASS_Encode_Start)
2:not stop bassenc
3:encode ogg to wave
4:stop bassenc(same HENCODE Return by BASS_Encode_Start)
but result only have mp3 file to wave,another file not output to same wave file,how about?

Why couldn't you use the BASSmix add-on.
With BASSmix you should be able to simply join two streams into one.
You simply need to add the second one to the mixer once the first one ends.
This can either be done by a SYNCPROC or by using BASS_Mixer_StreamAddChannelEx.

[simon1]

in fact I not to want mix two files, maybe many files
so I think bassenc should do this job not use bassmix,
but bassenc seems not can keep handle to contiue write next files

BASSenc can not mix multiple files. So I suggest you use BASSmix to mix/join multiple file and then use BASSenc on the mixer stream to encode the result...

how BASS_Mixer_StreamAddChannelEx work?

 for i := 0 to Count-1 do
 begin
 if i=0 then
 BASS_Mixer_StreamAddChannel(mixchan,sourcechan,BASS_STREAM_AUTOFREE) else
 begin
 PreBytes:=PreBytes+BASS_ChannelGetLength(sourcechan[i-1],BASS_POS_BYTE);
 BASS_Mixer_StreamAddChannelEx(MixChan,sourcechan,BASS_STREAM_AUTOFREE,PreBytes,0);
 end;
end;
wrong! result have silent,
IE,if first file have 4:00 then result wil get
first file+4:00 silent+second files
if use PreBytes=0 result same as BASS_Mixer_StreamAddChannel
how do?

If the sources all have the same sample format (eg. stereo 44100hz or whatever), then you can actually do this without BASSmix; you just need to use BASS_Encode_SetChannel at the end of each source to move the encoder to the next source.

If the sources have varying samples formats, then you should use BASSmix (and feed the mixer to BASSenc) so that they are resampled to a consistent format. Here's an example of using BASSmix for gapless playback (or encoding)...

If you are doing it in .NET see the audio joiner sample. in the bassNet download. It does what you want.

Thank you,now work
but there is a problem
if a file have large like 10 minutes
second file have 40 minutes
now i want to join it but part join
first large file I only want to join use 5 minutes
and second file I use 25 minutes
but I find there is a problem
BASS_Mixer_StreamAddChannelEx not work
for first file 0 to 5 minutes, but output file
5-10 minutes mix second file 25 minutes like
 (I want)
0--------5----------10 first file
             0-----------------25------------40 second file
                 (I want)
output file also 30 miniutes but for first file 5-10 minutes still into output file
BASS_Mixer_StreamAddChannelEx(mixchan,sourcechan[1],BASS_MIXER_NORAMPIN or BASS_STREAM_AUTOFREE,0,el);
el=5 minutes bytes
what's wrong?

[simon1]

Ian
Any Idea?

[simon1]

ok,I have a input wrong  on el=5 minutes bytes
BASS_Mixer_StreamAddChannelEx work fine
