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

M4A is an AAC-based audio format common on Apple devices and iTunes — better quality than MP3 at the same size.
M4A plays on Apple devices, iTunes and most modern players.
DDS (DirectDraw Surface) is Microsoft's texture format for games and 3D apps, storing compressed images with mipmaps that GPUs read directly.
DDS opens in game engines, GIMP (with a plugin), Photoshop (with the NVIDIA plugin) and texture tools; convert to PNG to view normally.
No. Audio and images are fundamentally different, so there's nothing to convert. You can convert your M4A to MP3, WAV or AAC instead.
Maybe a waveform/album-art image, or adding this audio to a video — those are separate tools, not a M4A→DDS conversion.
M4A converts cleanly to MP3, WAV or AAC — free, no sign-up, no watermark.
