Just like the most commonly used video formats we posted yesterday, we have the most common or popularly used audio formats used in today’s computers and devices for audio playback.
We have lot many audio formats and codecs used across the devices, thus here is a list explaining the most commonly used ones and their purpose:
1. AIFF – standard audio format used by devices like Apple.
2. AAC – Advanced Audio Coding, based on MPEG-2 and MPEG-4 standards.
3. AMR – Adaptive Multi Rate, mostly used for speech audio.
4. AU – standard format used by Java, Unix and Sun.
5. MID/MIDI – not an audio codec but used for musical notes or ringtones.
6. FLAC – Free Lossless Audio Codec, lossless and pure audio format having no audio compression.
7. MMF – used in ringtones mostly by brands like Samsung.
8. MP3 – MPEG Audio Layer 3, most common and famously used audio codec.
