Lame as a lib.

Reply Threaded

Hi, I'm using Lame as a library and I'm running into a bunch of problems.
How can I subscribe to this list?

The call sequence I'm using is roughly: lame_init(), lame_set_num_samples(),
lame_set_num_channels(), lame_set_in_samplerate(), lame_init_params(),
lame_encode_buffer_int(), lame_encode_flush(), lame_close().

Thanks!

- Daniel

Hi, thanks for the response.

Aparently it all succeeds, but when I listen to the output mp3 file it
appears to be rescaled to half the time, with the corresponding increase in
frequencies and pitch.

What I would like to know is, what am I doing wrong or what am I missing.

Thanks!

Maybe you are reading in every second sample from input file,
which would result in double speed playback:
- test: write out what you read as raw PCM and listen to the result
If the playback isn't just at double speed, but distortet, maybe
there is something wrong in the way you count the samples read in.
- compare yours with our code in frontend/main.c and frontend/get_audio.c

Ciao Robert

Hi, Robert, all

Thanks for the response... It took me some time to find a really dodgy bug
in my code interpreting the wave files. That's fixed now. However, I now
get this message:

strange error flushing buffer ...

Any pointers regarding where should I look into?

Thanks again!

- Daniel
