Trait Implementations

impl Decoder for MecompDecoder

fn decode(&self, path: &Path) -> AnalysisResult<ResampledAudio>

A function that should decode and resample a song, optionally extracting the song’s metadata such as the artist, the album, etc.

The output sample array should be resampled to f32le, one channel, with a sampling rate of 22050 Hz. Anything other than that will yield wrong results.

fn analyze_path<P: AsRef<Path>>(&self, path: P) -> AnalysisResult<Analysis>

Returns a decoded song’s Analysis given a file path, or an error if the song could not be analyzed for some reason.

fn analyze_paths<P: Into<PathBuf>, I: Send + IntoIterator<Item = P>>( &self, paths: I, callback: Sender<(PathBuf, AnalysisResult<Analysis>)>, ) -> Result<(), SendError<()>>

where Self: Sync + Send,

Analyze songs in paths in parallel across all logical cores, and emits the AnalysisResult<Analysis> objects (along with the Path they correspond to) through the provided callback channel.

fn analyze_paths_with_cores<P: Into<PathBuf>, I: IntoIterator<Item = P>>( &self, paths: I, number_cores: NonZeroUsize, callback: Sender<(PathBuf, AnalysisResult<Analysis>)>, ) -> Result<(), SendError<()>>

where Self: Sync + Send,

Analyze songs in paths in parallel across number_cores threads, and emits the AnalysisResult<Analysis> objects (along with the Path they correspond to) through the provided callback channel.

fn process_songs_with_cores( &self, paths: &[PathBuf], callback: ProcessingCallback, number_cores: NonZeroUsize, model_config: ModelConfig, ) -> AnalysisResult<()>

where Self: Sync + Send,

Process raw audio samples in audios, and yield the Analysis and Embedding objects through the provided callback channel. Parallelizes the process across number_cores CPU cores.

fn process_songs( &self, paths: &[PathBuf], callback: ProcessingCallback, model_config: ModelConfig, ) -> AnalysisResult<()>

where Self: Sync + Send,

Process raw audio samples in audios, and yield the Analysis and Embedding objects through the provided callback channel. Parallelizes the process across all available CPU cores.
