Enum RecordingFormat 

Source 
pub enum RecordingFormat {
    Wav,
    Flac,
}
Expand description

The file format a recording is written in.

Both hold the same quantized samples: a WAV is a short header in front of them, a FLAC stream is them compressed losslessly. A caller picks one the same way it picks an image format — by the extension of the file it names, or by the format argument of the tool that answers inline.

Variants§

§

Wav

A 16-bit PCM RIFF/WAVE file.

§

Flac

A lossless FLAC stream.

Implementations§

Source§

impl RecordingFormat

Source

pub const DEFAULT: Self = Self::Flac

The format a recording is written in when its caller names none.

FLAC is it because it is the smaller answer to carry across a transport and the one the stored baselines are compared in.

Source

pub fn from_name(name: &str) -> Result<Self, RecordingError>

The format name names, which is an extension or a tool argument and so is matched without regard to case.

§Errors

Returns an error when name names a format the recorder cannot write.

Source

pub fn of(file_name: &str) -> Result<Self, RecordingError>

The format the extension of file_name names.

§Errors

Returns an error when file_name has no extension, or when the extension names a format the recorder cannot write.

Source

pub fn mime_type(self) -> &'static str

The format as a MIME type, for the audio content block a tool that answers inline sends it in.

Source

pub fn encode( self, format: AudioFormat, samples: &[f32], ) -> Result<Vec<u8>, RecordingError>

Encode interleaved samples in this format.

§Errors

Returns an error when the FLAC encoder rejects the samples.
