Crate aus

This is a crate for audio processing and analysis in Rust, combining new functionality with aggregated functionality from other existing crates. For example, this crate provides wrappers for rustfft, allowing a FFT to be performed with a single function call. It also has a STFT/ISTFT function pair. It also has built-in window generation in the style of numpy. And there are implementations of spectral feature extraction, such as calculating spectral centroid, entropy, slope, etc.

Structs

• AudioFile
  Represents an audio file. Samples are always stored in f64 format, regardless of their original format on disk.

Enums

• AudioError
  Represents an error for audio files.
• AudioFormat
  Represents an audio format (fixed (S) or float (F)).
• WindowType
  Represents a window type.

Functions

• generate_window
  Gets the corresponding window for a provided WindowType and window size.
• generate_window_bartlett
  Creates a Bartlett window of size window_length.
• generate_window_blackman
  Creates a Blackman window of size window_length.
• generate_window_hamming
  Creates a Hamming window of size window_length.
• generate_window_hanning
  Creates a Hanning window of size window_length.
• generate_window_rectangular
  Creates a rectangular window of size window_length.
• mixdown
  Mixes an audio file down to mono. This will mix all channels down to the first one, and delete the remaining channels. It is performed in-place, so you will lose data.
• read
  Reads an audio file. Courtesy of symphonia. Supports WAV and AIFF, and (hopefully) all other Symphonia formats. Note that if you are reading a mp3 file, you may need to set the bits_per_sample and audio_format if you plan to write the file using the write function in this module.
• write
  Writes a WAV audio file to disk. Courtesy of hound. This writer will check to verify that the following are correct:
