Is there any way to specify the sample and bit rate when capturing sound with DirectShow? Thanks in advance! · Are you sure it is the right output pin of the audio capture device? Meaning, the audio device may have more then one output pin. How do you find the output pin (in code). Maybe, if there's more then one output pin on the filter, you should ...

Some time later, the capture filter senses Directshow is consuming samples too rapidly, and tries to set a timestamp of some time in the future, which the audio renderer completely ignores. I can, as a test, suddenly tell a sample it must not be rendered until 20 secs in the future (StreamTime() + UNITS), and again the renderer just ignores it.

The first pair would have an AUDIO_STREAM_CONFIG_CAPS capability structure saying you support a minimum of 11,025 to a maximum of 22,050 samples per second with a granularity of 11,025 samples per second (granularity is the difference between supported values); an 8-bit minimum to a 16-bit maximum bits per sample with a granularity of 8 bits per …

Each AC-3 frame embeds data for 6 * 256 samples. Sampling rate can be 32 kHz, 44.1 kHz or 48 kHz (as defined by AC-3 specification Digital Audio Compression Standard (AC-3, E-AC-3) ). The frames themselves do not carry timestamps, so you needs to assume continuous stream and increment time stamps respectively.
