An image stores pixels; an audio file stores a sound waveform. Neither contains the other, so no tool can turn a picture into a sound recording.
Looking to turn a THM into M4A? Here's the honest answer — and the conversions that actually work.

M4A plays on Apple devices, iTunes and most modern players.

THM converts cleanly to PNG, JPG or TIFF — free, no sign-up, no watermark.
