Spectrogram obtained with a standard Constant-Q Sliding Discrete Fourier Transform. Horizontally: time (10 s). Vertically: frequency, logarithmically spaced, from 20 Hz at the bottom to 20 kHz at the top, for a sampling rate of 44.1 kHz. Luminance: 0.5 dB per 8-bit step. The CQSDFT here is the Hann window version, Q = 74 (very high).

Spectrogram obtained with the modified Constant-Q Sliding Discrete Fourier Transform (oscillator but no correction). Horizontally: time (10 s). Vertically: frequency, logarithmically spaced, from 20 Hz at the bottom to 20 kHz at the top, for a sampling rate of 44.1 kHz. Luminance: 0.5 dB per 8-bit step.

I found a nice improvement to the Constant-Q Sliding DFT¹.

Using single precision calculation (32-bit float) generates some remanent noise because of the recursive nature of the algorithm: a running sum combined with complex rotations.

Replacing the […]
