Detailed Description

Utility class for resampling audio data.

Method Documentation

defaultLowPassOrder

+ (int) defaultLowPassOrder

Gets the default low pass order.

factor

- (double) factor

Gets the resampling factor.

getOutputLengthWithInput:

- (int) getOutputLengthWithInput:

(FMLiveSwitchDataBuffer *)

input

Gets the length of the output given an input set.

Parameters

input

The input.

initWithFactor:

- (instancetype) initWithFactor:

(double)

factor

Initializes a new instance of the FMLiveSwitchResampler class.

Parameters

factor

The resampling factor.

initWithSourceClockRate:targetClockRate:

- (instancetype) initWithSourceClockRate:		(int)	sourceClockRate
targetClockRate:		(int)	targetClockRate

Initializes a new instance of the FMLiveSwitchResampler class.

Parameters

sourceClockRate	The source clock rate.
targetClockRate	The target clock rate.

resamplerWithFactor:

+ (FMLiveSwitchResampler*) resamplerWithFactor:

(double)

factor

Initializes a new instance of the FMLiveSwitchResampler class.

Parameters

factor

The resampling factor.

resamplerWithSourceClockRate:targetClockRate:

+ (FMLiveSwitchResampler*) resamplerWithSourceClockRate:		(int)	sourceClockRate
targetClockRate:		(int)	targetClockRate

Initializes a new instance of the FMLiveSwitchResampler class.

Parameters

sourceClockRate	The source clock rate.
targetClockRate	The target clock rate.

resampleWithInput:output:

- (bool) resampleWithInput:		(FMLiveSwitchDataBuffer *)	input
output:		(FMLiveSwitchDataBuffer *)	output

Resamples the given audio buffer.

Parameters

input	The input to resample.
output	The output to target.

resampleWithInput:output:lastBatch:

- (bool) resampleWithInput:		(FMLiveSwitchDataBuffer *)	input
output:		(FMLiveSwitchDataBuffer *)	output
lastBatch:		(bool)	lastBatch

Resamples the given audio buffer.

Parameters

input	The input to resample.
output	The output to target.
lastBatch	Whether or not this is the last batch. If true, input will be read to the end.

Returns

true if the resampling operation was successful; otherwise, false.

setDefaultLowPassOrder:

+ (void) setDefaultLowPassOrder:

(int)

value
