Class AudioDeviceInfo

Namespace

AudioDeviceLib

Assembly

AudioDeviceLib.dll

An immutable snapshot of an AudioDevice's identifying information, detached from the live Core Audio COM object. Create one with ToDeviceInfo().

public sealed record AudioDeviceInfo : IEquatable<AudioDeviceInfo>

Inheritance

object

AudioDeviceInfo

Implements

IEquatable<AudioDeviceInfo>

Inherited Members

object.Equals(object)

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

All properties are captured when the snapshot is taken and never change, so an instance is safe to read from any thread, keep, or store - including after the originating AudioDevice has been disposed.

AudioDeviceKind

Name

Friendly name, e.g. "Speakers (Realtek High Definition Audio)".

public string Name { get; }

Property Value

string

State

Current state of the endpoint.

public DeviceState State { get; }

Property Value

DeviceState

Methods

Equals(AudioDeviceInfo?)

Compares endpoint IDs without regard to case.

public bool Equals(AudioDeviceInfo? other)

Parameters

other AudioDeviceInfo

The endpoint to compare.

Returns

bool

Whether both instances identify the same endpoint.

GetHashCode()

Serves as the hash function, derived from Id.

public override int GetHashCode()

int

A hash code for this endpoint snapshot.

ToString()
