CDA to M4A: Convert Audio from CDA(Audio CD Track) to M4A(MPEG-4 Audio) with River Past Audio CD Ripper, CDA2M4A converter, conversion

What is CDA?

The audio tracks on audio CDs are represented as .cda files. It is not a real file. Instead, it is a track of uncompressed audio data at 44.1khz with stereo channels.

What is M4A?

Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio.

To encode MPEG-4 audio, you need to have River Past MPEG-4 Booster Pack in addition to your audio software.
