Amplitude-independent window sizes in audio encoding

A computer program product tangibly embodied in a non-transitory storage medium, the computer program product including instructions that when executed by a processor cause the processor to perform operations, the operations comprising:

• receiving a first signal corresponding to a first flow of acoustic energy;
• applying a transform to the received first signal using at least a first amplitude-independent window size at a first frequency and a second amplitude-independent window size at a second frequency, the second amplitude-independent window size improving a temporal response at the second frequency, wherein the second frequency is subject to amplitude reduction due to a resonance phenomenon associated with the first frequency;
• and
• storing a first encoded signal, the first encoded signal based on applying the transform to the received first signal.
