[Unreleased]

Changed

• Update cpal to v0.16.

Version [0.21] (2025-07-12)

Added

• Added Source::amplify_decibel() method to control volume by decibels.
• Added Source::amplify_normalized() method to perceptually modify volume.
• Adds a function to write a Source to a wav file, enable the wav_output feature and see output_to_wav.
• Output audio stream buffer size can now be adjusted.
• Sources for directly generating square waves, triangle waves, square waves, and sawtooths have been added.
• An interface for defining SignalGenerator patterns with an fn, see GeneratorFunction.
• Minimal builds without cpal audio output are now supported. See README.md for instructions. (#349)
• Added Sample::is_zero() method for checking zero samples.
• Added DecoderBuilder for improved configuration.
• Added Pausable::is_paused() method for checking if source is paused.
• Using Decoder::TryFrom for File now automatically wraps in BufReader and sets byte_len. TryFrom<Cursor<T>> and TryFrom<BufReader> are also supported.
• Added Source::distortion() method to control distortion effect by gain and threshold.
• Added OutputStream::config() method to access an OutputStream's OutputStreamConfig once an OutputStream has been built.
• Added OutputStreamConfig::channel_count(), OutputStreamConfig::sample_rate(), OutputStreamConfig::buffer_size() and OutputStreamConfig::sample_format() getters to access an OutputStreamConfig's channel count, sample rate, buffer size and sample format values.
• Added Source::limit() method for limiting the maximum amplitude of a source.
• Added more noise generators: WhiteGaussian, WhiteTriangular, Blue, Brownian, Violet, and Velvet.

Changed

• Breaking: OutputStreamBuilder should now be used to initialize an audio output stream.
• Breaking: OutputStreamHandle removed, use OutputStream and OutputStream::mixer() instead.
• Breaking: DynamicMixerController renamed to Mixer, DynamicMixer renamed to MixerSource.
• Breaking: Sink::try_new renamed to connect_new and does not return error anymore. Sink::new_idle was renamed to new.
• Breaking: symphonia::SeekError has a new variant AccurateSeekNotSupported
