    • resample input audio data to any target frequency.; • encode such data in IMA ADPCM format; • save the output bitstream as unformatted raw data. The sample command below shows the input parameters used to resample data to: • target frequency 15625 Hz • reduce volume by -12 dB • compress data by using the IMA ADPCM codec.

    IMA/DVI ADPCM is a standard that compresses 16-bit sound data into only 4-bits. It is thought to be faster then Microsoft's ADPCM implementation. Source for a 32 kbits/sec ADPCM implementation, assumed to be compatible with Intel's DVI audio format, can be ftp'ed from ftp://ftp.cwi.nl/pub/audio/adpcm.shar .

    ADPCM was also used by Interactive Multimedia Association for development of legacy audio codec known as ADPCM DVI, IMA ADPCM or DVI4, in the early 1990s. Split-band or subband ADPCM. G.722 is an ITU-T standard wideband speech codec operating at 48, 56 and 64 kbit/s, based on subband coding with two channels and ADPCM coding of each.
