API Reference
Initialization
# From file
converter = AudioConverter("audio.wav")
Settings
converter.bitrate(192) # kbps (for lossy formats)
converter.sample_rate(44100) # Hz
converter.channels(2) # 1=mono, 2=stereo
converter.normalize(True) # Normalize volume
Conversion
# Convert to format (inferred from extension)
converter.convert("output.mp3")
# Explicit format
converter.convert("output", format="mp3")
Batch Processing
# Convert all files in directory
AudioConverter.batch_convert(
input_dir="./wavs",
output_dir="./mp3s",
format="mp3",
bitrate=320
)
