Fields

crc32: Option<Crc32>

Optional CRC-32 element for integrity checking.

void: Option<Void>

void element, useful for reserving space during writing.

sampling_frequency: SamplingFrequency

Sampling frequency in Hz.

output_sampling_frequency: Option<OutputSamplingFrequency>

Real output sampling frequency in Hz (used for SBR techniques). The default value for OutputSamplingFrequency of the same TrackEntry is equal to the SamplingFrequency.

channels: Channels

Numbers of channels in the track.

bit_depth: Option<BitDepth>

Bits per sample, mostly used for PCM.

emphasis: Emphasis

Audio emphasis applied on audio samples. The player MUST apply the inverse emphasis to get the proper audio samples.

• 0 - No emphasis,
• 1 - CD audio,
• 2 - reserved,
• 3 - CCIT J.17,
• 4 - FM 50,
• 5 - FM 75,
• 10 - Phono RIAA,
• 11 - Phono IEC N78,
• 12 - Phono TELDEC,
• 13 - Phono EMI,
• 14 - Phono Columbia LP,
• 15 - Phono LONDON,
• 16 - Phono NARTB

Trait Implementations

impl Clone for Audio

fn clone(&self) -> Audio

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Audio

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Audio

fn default() -> Audio

Returns the “default value” for a type.

impl Element for Audio

const ID: VInt64

EBML ID of the element.

fn decode_body(buf: &mut &[u8]) -> Result<Self>

Decode the body of the element from a buffer.

fn encode_body<B: BufMut>(&self, buf: &mut B) -> Result<()>

Encode the body of the element to a buffer.

const HAS_DEFAULT_VALUE: bool = false

Whether the element has a default value, as per Matroska specification. If true, and the element is missing in a master element, it should be treated as if it were present with the default value. If false, and the element is missing in a master element, it should be treated as an error.

impl PartialEq for Audio

fn eq(&self, other: &Audio) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
