[quote="/Chris":1ecvnpx0]I’ve translated the VB module to Delphi and made a working Lame sample.
It’s using a DSP-callback

Ok, I’ve looked at your example and wrote a DSP callback, but what I’m having trouble with is writing to a file. Whenever I write to a file it opens it, writes a chunk of data, and then closes it. But then when I open it again to write another chunk of data it erases all the data that was there before. So, I’m having trouble writing to a file inside a DSP callback, because unlike your example I’m not dealing with a sample, but with a stream, so I can’t use Lock and Unlock etc. to access the pcm data. Is there a way in VB to write to the end of the file instead of writing over all other data?
Ok, I’m having more problems with MP3 encoding in VB. I posted my example and I was wondering if you (KarLKoX) could take a look at it. The problem I’m having isnt with Lame, but whenever I start encoding I get an ilegal operation error with FMOD. And afterwards the output MP3 file is 392 Bytes, so I know its writing something out! :-?. [url=http://members.aol.com/libertyed1986/MP3Encoder.zip:23882dam]Heres[/url:23882dam] the link. Thanks!
[url=http://starnetasso.free.fr/Upload/MP3Encoder.rar:12fvoebi]Here[/url:12fvoebi] is the updated version, no more craches 😀
In case you didn’t read comments :
– Lame is updated to 3.95 (previously it was 3.91),
– Lame is now in __stdcall naming convention,
– Lame needs short int (integer from +- 32768) so don’t use the fpu mixer,
– I don’t know how to get more than 1024 samples in a DSP (even when i increase the buffersize), the mp3 is shorter than the original.
Not built into FMOD, no, but it wouldn’t be hard to feed BladeEnc.dll or lame_enc.dll from a DSP unit while the CDDA stream is playing. A good place to start would be the FMOD cddarip example. Instead of just doing an fwrite in the DSP callback, you’d pass the chunk of data to BladeEnc or lame.
hmmm, I’m still getting the “Bad DLL calling convention” error. Maybe it has to do with the module I wrote. I just converted it from your purebasic example into VB. Have a look at it [url=http://members.aol.com/libertyed1986/modLAME.bas:3658welz]Here[/url:3658welz].

You can extract audio digitally, and save it directly in MP3
NERO has a built-in MP3 encoder :)[/quote:2aigj53f]
lol ! He want to code it using fmod and the lame encoder and he is not searching for a tool doing cdda extraction
Btw, eac is a better choice 😉
