The spectrograms below show the frequency representation of the signal, where the x-axis corresponds to the frequency of the original waveform (in log scale), y-axis the frequency of the plotted waveform, and color intensity the amplitude. sample_rate = 48000 resample_rate = 32000 waveform = get_sine_sweep(sample_rate) plot_sweep(waveform, sample_rate, title="Original …

Using a larger lowpass_filter_width provides a sharper, more precise filter, but is more computationally expensive. sample_rate = 48000 resample_rate = 32000 resampled_waveform = F.resample(waveform, sample_rate, resample_rate, lowpass_filter_width=6) plot_sweep(resampled_waveform, resample_rate, title="lowpass_filter_width=6") …
audioresample - GStreamer
https://gstreamer.freedesktop.org/documentation/audioresample/index.html
audioresample resamples raw audio buffers to different sample rates using a configurable windowing function to enhance quality. By default, the resampler uses a reduced sinc table, with cubic interpolation filling in the gaps. This ensures that the table does not become too big. However, the interpolation increases the CPU usage considerably.

Every compressed format of an audio codec has a specific sample rate and sample size. These do not need to match the settings of the input format or output format. If an input format has different settings than the compressed format described in the profile, the writer will resample the audio, during the encoding process, to match the compressed format.

It also is quite flexible and is often able to change to a different channel count or bit depth at the same time. Here's a code sample that resamples an MP3 file (usually 44.1kHz) down to 16kHz. The MediaFoundationResampler takes an IWaveProvider as input, and a desired output format:

Resample in iZotope's RX audio repair software allows you to convert an audio file from one sampling rate to another with our renowned Sample Rate Conversion (SRC). SRC is a necessary process when converting material from one sampling rate (such as studio-quality 96 kHz or 192 kHz) to another rate (such as 44.1 kHz for CD or 48 kHz for video).
