AT_ERRCOUNT nErrcount; /* Number of errors on stack */ HIGMULT hMult; /* Multimedia instance handle */ AT_UINT nSampleRate; /* Sample rate of audio */ AT_UINT nBitsPerSample; /* Bits per sample */ AT_UINT nChannels; /* Number of channels */ nErrcount = IG_mult_audio_format_get(hMult, &nSampleRate, &nBitsPerSample, &nChannels); |
Note that audio retrieved using IG_mult_audio_get() is always in uncompressed PCM format. If the multimedia instance does not contain audio, an error will occur.
