M, -mmap Use memory-mapped (mmap) I/O mode for the audio stream. Record/playback process will run until it is killed. The default is zero, so if this options is omitted then the s, -samples=# Interrupt after transmission of # PCM frames. Either '-d' or '-s' option is availableĮxclusively. Zero, so if this option is omitted then the record/playback process will d, -duration=# Interrupt after # seconds. Specified is less than 300, it is taken as the rate in kilohertz. f dat (16 bit little endian, 48000, stereo) f cdr (16 bit big endian, 44100, stereo) f cd (16 bit little endian, 44100, stereo) Some of these may not be available on selected hardware S24_BE U24_LE U24_BE S32_LE S32_BE U32_LE U32_BE FLOAT_LE FLOAT_BEįLOAT64_LE FLOAT64_BE IEC958_SUBFRAME_LE IEC958_SUBFRAME_BE MU_LAW A_LAW Recognized sample formats are: S8 U8 S16_LE S16_BE U16_LE U16_BE S24_LE If this parameter is omitted the WAVEįormat is used.
