What is AAC and why convert it to a universal format?
AAC (Advanced Audio Coding) is a modern codec widely used by iPhone, iTunes, and platforms like YouTube or Spotify. Files are often saved as .m4a, a container that carries AAC audio. While AAC offers great quality at low bitrates, many older devices and some car systems don’t play it well, so converting to MP3 ensures near-universal compatibility and makes sharing or editing easier.
Benefits of the resulting format
- Works on phones, computers, TVs, and car stereos without extra tweaks.
- Simple to send via WhatsApp, email, or cloud services.
- Lets you control final size by choosing the bitrate.
Recommended quality
- Voice: 64–128 kbps (mono or light stereo).
- Music: 192 kbps or higher for better fidelity.
- Very small file: 64 kbps for quick sharing.
If unsure, 128 kbps is a solid balance between size and clarity.
