Menginstal PyDub

$ pip install pydub

Jika memakai selain .wav, instal ffmpeg via ffmpeg.org

Kelas utama PyDub: AudioSegment

# Impor kelas utama PyDub
from pydub import AudioSegment

# Impor file audio
wav_file = AudioSegment.from_file(file="wav_file.wav", format="wav")

# Parameter format hanya untuk keterbacaan
wav_file = AudioSegment.from_file(file="wav_file.wav")

type(wav_file)

pydub.audio_segment.AudioSegment

Memutar file audio

# Instal simpleaudio untuk memutar wav
$pip install simpleaudio

# Impor fungsi play
from pydub.playback import play

# Impor file audio
wav_file = AudioSegment.from_file(file="wav_file.wav")

# Putar file audio
play(wav_file)

Parameter audio

# Impor file audio
wav_file = AudioSegment.from_file(file="wav_file.wav")
two_speakers = AudioSegment.from_file(file="two_speakers.wav")

# Cek jumlah kanal
wav_file.channels, two_speakers.channels

1, 2

wav_file.frame_rate

Parameter audio

# Cari jumlah byte per sampel
wav_file.sample_width

# Cari amplitudo maksimum
wav_file.max

Parameter audio

# Durasi file audio dalam milidetik
len(wav_file)

Mengubah parameter audio

# Ubah ATTRIBUTENAME dari AudioSegment ke x
changeed_audio_segment = audio_segment.set_ATTRIBUTENAME(x)

# Ubah lebar sampel ke 1
wav_file_width_1 = wav_file.sample_width(1)
wav_file_width_1.sample_width

Mengubah parameter audio

# Ubah sample rate
wav_file_16k = wav_file.frame_rate(16000)
wav_file_16k.frame_rate

# Ubah jumlah kanal
wav_file_1_channel = wav_file.set_channels(1)
wav_file_1_channel.channels
