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

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

getBitrateRange

public Range<Integer> getBitrateRange ()

Returns the range of supported bitrates in bits/second.

Returns
`Range<Integer>`

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`
