In plugin processor a process block which takes a buffer, I would like to get the sample data however the method has been deprecated, when I try to use getReaderPointer i get an error.
// this code is from Joshua D. Reiss and Andrew P. McPherson
void WahwahAudioProcessor::processBlock (AudioSampleBuffer& buffer, MidiBuffer& midiMessages)
{
// Helpful information about this block of samples:
const int numInputChannels = getNumInputChannels(); // How many input channels for our effect?
const int numOutputChannels = getNumOutputChannels(); // How many output channels for our effect?
const int numSamples = buffer.getNumSamples(); // How many samples in the buffer for this block?
int channel;
// Go through each channel of audio that's passed in
for (channel = 0; channel < jmin(numInputChannels, numWahFilters_); ++channel)
{
// channelData is an array of length numSamples which contains the audio for one channel
// getSampleData deprecated - use getReadPointer
float* channelData = buffer.getReadPointer(channel);
// Run the samples through the IIR filter whose coefficients define the parametric
// equaliser. See juce_IIRFilter.cpp for the implementation.
wahFilters_[channel]->processSamples(channelData, numSamples);
}
// Go through the remaining channels. In case we have more outputs
// than inputs, or there aren't enough filters, we'll clear any
// remaining output channels (which could otherwise contain garbage)
while(channel < numOutputChannels)
{
buffer.clear (channel++, 0, buffer.getNumSamples());
}
