Does IPP support MPEG-2.5 Audio encoding?

Is it possible to do MP3 encoding of 8KHz audio using IPP? I only found support for MPEG-2.5 8KHz audio in MP3 decoder.

I tried to use audio_codec_con sample to convert an 8KHz PCM file into MP3. It looks like the fixed point version cannot convert it at all, and that floating point version converts the file but upsamples it to 16 Khz (with some horrible audio artifacts). Is MPEG-2.5 audio encoding implemented at all?

Hello,

o, we do not support MPEG2.5 encoding, we do support only decoding for that case. Wemay recommend you to useAMRWB codec which is more applicable for that case.

Vladimir
