Sample format
Recognized sample formats are: S8 U8 S16_LE S16_BE U16_LE U16_BE S24_LE S24_BE U24_LE U24_BE S32_LE S32_BE U32_LE U32_BE FLOAT_LE FLOAT_BE
FLOAT64_LE FLOAT64_BE IEC958_SUBFRAME_LE IEC958_SUBFRAME_BE MU_LAW A_LAW IMA_ADPCM MPEG GSM SPECIAL S24_3LE S24_3BE U24_3LE U24_3BE S20_3LE
S20_3BE U20_3LE U20_3BE S18_3LE S18_3BE U18_3LE
Some of these may not be available on selected hardware
The available format shortcuts are:
-f cd (16 bit little endian, 44100, stereo) [-f S16_LE -c2 -r44100]
-f cdr (16 bit big endian, 44100, stereo) [-f S16_BE -c2 -f44100]
-f dat (16 bit little endian, 48000, stereo) [-f S16_LE -c2 -r48000]
If no format is given U8 is used.
-d, --duration=#
Interrupt after # seconds. A value of zero means infinity. The default is zero, so if this option is omitted then the arecord process will run until it is killed.
-t, --file-type TYPE
File type (voc, wav, raw or au). If this parameter is omitted the WAVE format is used.

HowTo: Split MP3s by silence detection using mp3splt
https://blog.dornea.nu/2012/04/01/howto-split-mp3s-by-silence-detection-using-mp3splt/
mp3splt -s -p th=-40,min=6,rm
Parameters explanation:
'-s': silence mode; activate silence detection
'-p': specify arguments for the silence mode
'th=-40': threshold level (dB) to be considered silence
'min=6': minimum number of seconds to be considered as splitpoint
'rm': remove silence from splitted filesWhat worked for me
mp3splt -s -p th=-30,min=0.5,rm $1
Fix tracks not splitting
- Manually seek the silence in mplayer/mpv
- Note the silent areas
- Cut with ffmpeg ie.
- ffmpeg -i track.flac -ss 00:03:05 -to 00:06:00 -acodec copy track-cut1.flac
