* pcm: added pcm_convert_deinit(), pcm_resample_deinit()Max Kellermann2009-01-071-0/+5
| | | | | Free memory allocated by libsamplerate when the output or the decoder is closed.
* pcm_resample_fallback.c: replaced mpd_unused by G_GNUC_UNUSEDThomas Jansen2008-11-241-5/+5

* pcm_resample: implemented 24 bit resamplingMax Kellermann2008-10-231-0/+33
| | | | | | | Similar to pcm_resample_16(), implement pcm_resample_24(). The 24 bit implementation is very similar, but it uses src_int_to_float_array() instead of src_short_to_float_array() before sending data to libsamplerate.
* pcm_resample: eliminated "sample" local variablesMax Kellermann2008-10-231-9/+3
| | | | | Copy from source to destination buffer directly, don't use the temporary variables "lsample" and "rsample".
* pcm_resample: don't resample partial samplesMax Kellermann2008-10-231-0/+5
| | | | | Added assertions which ensure that there are no partial samples in the source buffer.
* pcm_resample: don't hard-code sample sizeMax Kellermann2008-10-231-1/+1
| | | | | | Use sizeof(sample) instead of hard-coding "2". Although we're in 16 bit right now, this will make code sharing easier when we support other sample sizes.
* pcm_utils: moved code to pcm_resample.cMax Kellermann2008-10-231-0/+61
Separate the resampling code from the rest of pcm_utils.c. Create two sub-libraries: pcm_resample_libsamplerate.c and pcm_resample_fallback.c.
