Enum AudioEncoding 

pub enum AudioEncoding {
    Pcm8bit = 3,
    Pcm16bit = 2,
    PcmFloat = 4,
}

Audio encoding format enumeration

Defines audio data encoding formats, i.e., how each audio sample is represented. Different encoding formats correspond to different audio quality and storage requirements.

Examples

use android_media::AudioEncoding;
let encoding = AudioEncoding::Pcm16bit;
assert_eq!(encoding.value(), 2);
assert_eq!(encoding.bytes_per_sample(), 2);

Variants

Pcm8bit = 3

8-bit PCM encoding - 1 byte per sample

Pcm16bit = 2

16-bit PCM encoding - 2 bytes per sample, most commonly used

PcmFloat = 4

32-bit float PCM encoding - 4 bytes per sample, provides higher dynamic range

Implementations

impl AudioEncoding

pub const fn value(&self) -> i32

Get the integer value of the encoding format

Returns

Returns the encoding format identifier in the Android system

Examples

use android_media::AudioEncoding;
assert_eq!(AudioEncoding::Pcm16bit.value(), 2);

pub const fn bytes_per_sample(&self) -> i32

Get the number of bytes per sample

Returns

Returns the number of bytes occupied by each audio sample in this encoding format

Examples

use android_media::AudioEncoding;
assert_eq!(AudioEncoding::Pcm8bit.bytes_per_sample(), 1);
assert_eq!(AudioEncoding::Pcm16bit.bytes_per_sample(), 2);
assert_eq!(AudioEncoding::PcmFloat.bytes_per_sample(), 4);

Trait Implementations

impl Clone for AudioEncoding

fn clone(&self) -> AudioEncoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AudioEncoding

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

Formats the value using the given formatter.

impl PartialEq for AudioEncoding

fn eq(&self, other: &AudioEncoding) -> 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.
