Record sound is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Record sound (mono 16-bit PCM) into an integer array.
PicoLisp
<lang PicoLisp>(in '(rec -q -c1 -tu16 - trim 0 2) # Record 2 seconds
(make (while (rd 2) (link @) ) ) )</lang>
Output:
-> (16767 19071 17279 ... 5503 9343 14719) # 96000 numbers
Python
<lang python>import pyaudio
chunk = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 1 RATE = 44100
p = pyaudio.PyAudio()
stream = p.open(format = FORMAT,
channels = CHANNELS, rate = RATE, input = True, frames_per_buffer = chunk)
data = stream.read(chunk) print [ord(i) for i in data]</lang>
Tcl
<lang tcl>package require sound
- Helper to do a responsive wait
proc delay t {after $t {set ::doneDelay ok}; vwait ::doneDelay}
- Make an in-memory recording object
set recording [snack::sound -encoding "Lin16" -rate 44100 -channels 1]
- Set it doing the recording, wait for a second, and stop
$recording record -append true delay 1000 $recording stop
- Convert the internal buffer to viewable numbers, and print them out
binary scan [$recording data -byteorder littleEndian] s* words puts [join $words ", "]
- Destroy the recording object
$recording destroy</lang>
