A class that supports querying the audio capabilities of a codec.

Summary

Public methods

Range<Integer> getBitrateRange()

Returns the range of supported bitrates in bits/second.

Range[]<Integer> getInputChannelCountRanges()
int getMaxInputChannelCount()

Returns the maximum number of input channels supported.

int getMinInputChannelCount()

Returns the minimum number of input channels supported.

Range[]<Integer> getSupportedSampleRateRanges()

Returns the array of supported sample rate ranges.

int[] getSupportedSampleRates()

Returns the array of supported sample rates if the codec supports only discrete values.

boolean isSampleRateSupported(int sampleRate)

Query whether the sample rate is supported by the codec.

Inherited methods

Public methods

getBitrateRange

public Range<Integer> getBitrateRange ()

Returns the range of supported bitrates in bits/second.

Returns
Range<Integer>

getInputChannelCountRanges

public Range[]<Integer> getInputChannelCountRanges ()

Returns
Range[]<Integer> This value cannot be null.

getMaxInputChannelCount

public int getMaxInputChannelCount ()

Returns the maximum number of input channels supported. Through Build.VERSION_CODES.R, this method indicated support for any number of input channels between 1 and this maximum value. As of Build.VERSION_CODES.S, the implied lower limit of 1 channel is no longer valid. As of Build.VERSION_CODES.S, getMaxInputChannelCount() is superseded by getInputChannelCountRanges(), which returns an array of ranges of channels. The getMaxInputChannelCount() method will return the highest value in the ranges returned by getInputChannelCountRanges()

Returns
int Value is between 1 and 255 inclusive

getMinInputChannelCount

public int getMinInputChannelCount ()

Returns the minimum number of input channels supported. This is often 1, but does vary for certain mime types. This returns the lowest channel count in the ranges returned by getInputChannelCountRanges().

Returns
int Value is between 1 and 255 inclusive

getSupportedSampleRateRanges

public Range[]<Integer> getSupportedSampleRateRanges ()

Returns the array of supported sample rate ranges. The array is sorted in ascending order, and the ranges are distinct.

Returns
Range[]<Integer>

getSupportedSampleRates

public int[] getSupportedSampleRates ()

Returns the array of supported sample rates if the codec supports only discrete values. Otherwise, it returns null. The array is sorted in ascending order.

Returns
int[]

isSampleRateSupported

public boolean isSampleRateSupported (int sampleRate)

Query whether the sample rate is supported by the codec.

Parameters
sampleRate int

Returns
boolean
