AudioSampleBuffer alignement

Jules, you may want to ensure proper alignment in allocateData in the same way you do that in setSize.

allocateData:
const size_t channelListSize = sizeof (Type*) * (size_t) (numChannels + 1);
allocatedBytes = (size_t) numChannels * (size_t) size * sizeof (Type) + channelListSize + 32;

setSize:
const size_t allocatedSamplesPerChannel = ((size_t) newNumSamples + 3) & ~3u;
const size_t channelListSize = ((sizeof (Type*) * (size_t) (newNumChannels + 1)) + 15) & ~15u;
