Summary
[edit]DescriptionMel-scale from 200 to 1500, in intervals of 50.ogg |
English: Mel-scale from 200 to 1500, in intervals of 50. Each note is played as a sine-wave, for 0.5 seconds.
```python import numpy as np from pydub import AudioSegment def mel_to_hz(m): return (10**(m/2595) - 1)*700 sample_rate = 44100 duration = 0.5 samples = [] for freq in [mel_to_hz(m) for m in range(200, 1501, 50)]: sample = (np.sin(2*np.pi*np.arange(sample_rate*duration)*freq/sample_rate)*32767).astype(np.int16) samples.append(sample) samples = np.concatenate(samples)
audio = AudioSegment(samples.tobytes(), frame_rate=sample_rate, sample_width=samples.dtype.itemsize, channels=1) audio ``` |
