A new method of transform encoding is presented which yields good quality voice at 9600 bits/sec. This method is far simpler to implement than similar coding techniques. The method incorporates the ears' insensitivity to the phase of the short-time spectrum. The log magnitude of the Discrete Fourier Transform is truncated and encoded using adaptive PCM. The phase is separately companded and encoded using PCM.
