# AudioProfile

*** ** * ** ***

` public class AudioProfile `   
` extends https://developer.android.com/reference/java/lang/Object ` ` implements https://developer.android.com/reference/android/os/Parcelable `

|---|---|
| [java.lang.Object](https://developer.android.com/reference/java/lang/Object) ||
| ↳ | android.media.AudioProfile |

<br />

*** ** * ** ***

An AudioProfile is specific to an audio format and lists supported sampling rates and channel masks for that format. An `https://developer.android.com/reference/android/media/AudioDeviceInfo` has a list of supported AudioProfiles. There can be multiple profiles whose encoding format is the same. This usually happens when an encoding format is only supported when it is encapsulated by some particular encapsulation types. If there are multiple encapsulation types that can carry this encoding format, they will be reported in different audio profiles. The application can choose any of the encapsulation types.

```

<br />

<br />

## Public methods

### describeContents

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int describeContents ()
```

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`, the return value of this method must include the `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### equals

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object o)
```

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is *reflexive*: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric*: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive*: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent*: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

An equivalence relation partitions the elements it operates on into *equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

<br />

| Parameters ||
|---|---|
| `o` | `Object`: the reference object with which to compare. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getChannelIndexMasks

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int[] getChannelIndexMasks ()
```

<br />

<br />

| Returns ||
|---|---|
| `int[]` | an array of channel index masks that are associated with the encoding format. This value cannot be `null`. <br /> |

### getChannelMasks

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int[] getChannelMasks ()
```

<br />

<br />

| Returns ||
|---|---|
| `int[]` | an array of channel position masks that are associated with the encoding format. This value cannot be `null`. <br /> |

### getEncapsulationType

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getEncapsulationType ()
```

The encapsulation type indicates what encapsulation type is required when the framework is using this format when playing to a device exposing this audio profile. When encapsulation is required, only playback with `https://developer.android.com/reference/android/media/AudioTrack` API is supported. But playback with `https://developer.android.com/reference/android/media/MediaPlayer` is not. When an encapsulation type is required, the `https://developer.android.com/reference/android/media/AudioFormat` encoding selected when creating the `https://developer.android.com/reference/android/media/AudioTrack` must match the encapsulation type, e.g AudioFormat.ENCODING_IEC61937 for AUDIO_ENCAPSULATION_TYPE_IEC61937.

<br />

| Returns ||
|---|---|
| `int` | an integer representing the encapsulation type. Value is one of the following: - `https://developer.android.com/reference/android/media/AudioProfile#AUDIO_ENCAPSULATION_TYPE_NONE` - `https://developer.android.com/reference/android/media/AudioProfile#AUDIO_ENCAPSULATION_TYPE_IEC61937` - `https://developer.android.com/reference/android/media/AudioProfile#AUDIO_ENCAPSULATION_TYPE_PCM` |

### getSampleRates

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int[] getSampleRates ()
```

<br />

<br />

| Returns ||
|---|---|
| `int[]` | an array of sample rates that are associated with the encoding format. This value cannot be `null`. <br /> |

### hashCode

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `https://developer.android.com/reference/java/util/HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### toString

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Returns a string representation of the object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string representation of the object. <br /> |

### writeToParcel

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void writeToParcel (Parcel dest, 
                int flags)
```

Flatten this object in to a Parcel.

<br />

| Parameters ||
|---|---|
| `dest` | `Parcel`: This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
