Defined in GI.GstAudio.Structs.AudioChannelMixer

Methods

wrappedPtrCalloc :: IO (Ptr AudioChannelMixer)

wrappedPtrCopy :: AudioChannelMixer -> IO AudioChannelMixer

noAudioChannelMixer :: Maybe AudioChannelMixer

A convenience alias for Nothing :: Maybe AudioChannelMixer.

Methods

free

audioChannelMixerFree

Arguments

:: (HasCallStack, MonadIO m)

=> AudioChannelMixer

mix: a AudioChannelMixer

-> m ()

Free memory allocated by mix.

isPassthrough

audioChannelMixerIsPassthrough

Arguments

:: (HasCallStack, MonadIO m)

=> AudioChannelMixer

mix: a AudioChannelMixer

-> m Bool

Returns: True is mix is passthrough.

Check if mix is in passthrough.

Only N x N mix identity matrices are considered passthrough, this is determined by comparing the contents of the matrix with 0.0 and 1.0.

As this is floating point comparisons, if the values have been generated, they should be rounded up or down by explicit assignment of 0.0 or 1.0 to values within a user-defined epsilon, this code doesn't make assumptions as to what may constitute an appropriate epsilon.

samples

audioChannelMixerSamples

Arguments

:: (HasCallStack, MonadIO m)

=> AudioChannelMixer

mix: a AudioChannelMixer

-> Ptr ()

in: input samples

-> Ptr ()

out: output samples

-> Int32

samples: number of samples

-> m ()

In case the samples are interleaved, in and out must point to an array with a single element pointing to a block of interleaved samples.

If non-interleaved samples are used, in and out must point to an array with pointers to memory blocks, one for each channel.

Perform channel mixing on inData and write the result to outData. inData and outData need to be in format and layout.
