Hello,
Does anyone know which tool or library i can use to decode audio data stored
in a ADPCM header-less file? (8kHz, 1 channel, (12,16,25 or 32) bit)
I've tried sox and libsamplerate, but both throws an error.
and with sndfile:
<code snip>
sfinfo.format = SF_FORMAT_IMA_ADPCM | SF_FORMAT_RAW;
sfinfo.samplerate = 8000;
sfinfo.channels = 1;
if ((fpr = sf_open ("data.adpcm", SFM_READ, &sfinfo)) == NULL)
...
</code snip>
Try one of the following sndfile formats with the RAW (from sndfile.h)
SF_FORMAT_GSM610 = 0x0020, /* GSM 6.10
encoding. */
SF_FORMAT_VOX_ADPCM = 0x0021, /* OKI /
Dialogix ADPCM */
SF_FORMAT_G721_32 = 0x0030, /* 32kbs
G721 ADPCM encoding. */
SF_FORMAT_G723_24 = 0x0031, /* 24kbs
G723 ADPCM encoding. */
SF_FORMAT_G723_40 = 0x0032, /* 40kbs
G723 ADPCM encoding. */
