Trait hound::Sample
[−]
[src]
pub trait Sample: Sized { fn write<W: Write>(self, writer: &mut W, bits: u16) -> Result<()>; fn read<R: Read>(
reader: &mut R,
_: SampleFormat,
bytes: u16,
bits: u16
) -> Result<Self>; fn as_i16(self) -> i16; }
A type that can be used to represent audio samples.
Via this trait, decoding can be generic over i8, i16, i32 and f32.
All integer formats with bit depths up to 32 bits per sample can be decoded
into i32, but it takes up more memory. If you know beforehand that you
will be reading a file with 16 bits per sample, then decoding into an i16
will be sufficient.
Required Methods
fn write<W: Write>(self, writer: &mut W, bits: u16) -> Result<()>
Writes the audio sample to the WAVE data chunk.
fn read<R: Read>(
reader: &mut R,
_: SampleFormat,
bytes: u16,
bits: u16
) -> Result<Self>
reader: &mut R,
_: SampleFormat,
bytes: u16,
bits: u16
) -> Result<Self>
Reads the audio sample from the WAVE data chunk.
fn as_i16(self) -> i16
Cast the sample to a 16-bit sample.
This does not change the value of the sample, it only casts it. The value is assumed to fit within the range. This is not verified, truncation may occur.
