API Reference — Adafruit CircuitPython wave Library 1.0 documentation

adafruit_wave.open(f, mode=None)

Open a wave file in reading (default) or writing (mode="w") mode.

The argument may be a filename or an open file.

In reading mode, returns a Wave_read object. In writing mode, returns a Wave_write object.

class adafruit_wave.Wave_read(f)

Used for wave files opened in read mode.

Do not construct directly, but call open instead.

close()

Close the file

getfp()

Get the underlying file object

getframerate()

Get the sample rate in Hz

getnchannels()

Get the number of channels (1 for mono, 2 for stereo)

getnframes()

Get the number of frames

getsampwidth()

Get the sample width in bytes

readframes(nframes)

Read frames of audio data

rewind()

Go back to the start of the audio data

setpos(pos)

Seek to a particular position in the audio data

tell()

Get the current position in the audio data

class adafruit_wave.Wave_write(f)

Used for wave files opened in write mode.

Do not construct directly, but call open instead.

close()

Close the file

getframerate()

Get the sample rate in Hz

getnchannels()

Get the number of channels (1 for mono, 2 for stereo)

getsampwidth()

Get the sample width in bytes

setframerate(framerate)

Set the sample rate in Hz

setnchannels(nchannels)

Set the number of channels (1 for mono, 2 for stereo)

setparams(params)

Set all parameters at once

setsampwidth(sampwidth)

Set the sample width in bytes

tell()

Get the current position in the audio data

writeframes(data)

Write data to the file and update the header if needed

writeframesraw(data)

Write data to the file without updating the header
