Unreleased

  • Add packed 24-bit sample types I24LE3, I24BE3, U24LE3 and U24BE3 to dasp_sample::types, corresponding to the ALSA S24_3LE, S24_3BE, U24_3LE and U24_3BE formats. Unlike I24/U24 these occupy exactly three bytes with an alignment of one, so packed 24-bit PCM can be reinterpreted as a slice of them without a copy. Out-of-range values wrap modulo 2^24.
  • Bump dasp_sample and dasp_frame to 0.11.1, and raise dasp_frame's requirement on dasp_sample to 0.11.1, as it now references the packed types by name and would not build against 0.11.0.
  • Renamed window-hanning to window-hann
  • Made IntoInterleavedSamples and IntoInterleavedSamplesIterator stop yielding samples when the underlying signal gets exhausted. This is a breaking change. The return type of the IntoInterleavedSamples#next_sample method was modified.

0.11.0 (2020-05-29)

  • Refactor the sample crate into a modular collection of crates under dasp.
  • Rename repository from sample to dasp, where dasp stands for digital audio signal processing.
  • Add a suite of useful feature gates:
    • Add std to all crates. Can be disabled in order to use no_std.
    • Add a all-features-no-std feature to dasp, dasp_envelope, dasp_interpolate, dasp_signal, dasp_slice and dasp_window. Enables all features within a no_std context.
    • dasp_envelope crate:
      • peak - enables peak detector implementation.
      • rms - enables RMS detector implementation.
    • dasp_interpolate crate:
      • floor - enables Floor Interpolate implementation.
      • linear - enables Linear Interpolate implementation.
      • sinc - enables Sinc Interpolate implementation.
    • dasp_signal crate:
      • boxed - enables Signal implementation for Box<dyn Signal>.
      • bus - enables SignalBus trait.
      • envelope - enables SignalEnvelope trait.
      • rms - enables SignalRms trait.
      • window - enables signal::window module.
      • window-hanning - enables hanning window constructor.
      • window-rectangle - enables rectangle window constructor.
    • dasp_slice crate:
      • boxed - enables conversions between boxed slices.
    • The dasp crate has a feature for each of the above.
  • Make Window trait generic over its phase and amplitude type. Update the dasp_signal::window module items accordingly.
  • Remove unsafe uninitialized ring buffer constructors.
  • Remove equilibrium() and identity() constructors from Sample and Frame traitsin favour of EQUILIBRIUM and IDENTITY associated consts.
  • Remove Frame::n_channels function in favour of Frame::CHANNELS associated const.
  • Add implementation of Frame for all primitive Sample types where each are assumed to represent a frame of a monophonic signal. This greatly simplifies working with monophonic signal sources as demonstrated in the updated dasp_signal crate.
