It depends.

kAudioFormatLinearPCM represents the whole family of linear PCM sample
formats. It would be the same only if the mFormatFlags field had the
kLinearPCMFormatFlagIsFloat, kLinearPCMFormatFlagIsBigEndian and
kLinearPCMFormatFlagIsPacked bits set and the the mBitsPerChannel field is
set to 32.
