Cdrdao records audio or data CD-Rs in disk-at-once (DAO) mode based on a textual description of the CD contents.
Advantages of Disk-At-Once (DAO) Recording:
Recording in disk-at-once mode writes the complete disc, i.e. lead-in, one or more tracks and lead-out, in a single step. The commonly used track-at-once (TAO) mode writes each track independently which requires link blocks between two tracks. Older CD-recorder models forced a two second pause (pre-gap) between two tracks whereas newer models allow adjusting of the pause length in TAO mode reducing the number of link blocks to a minimal amount. However, with TAO it is generally not possible to define the data that is written in pre-gaps. But exactly this feature makes audio CD recording interesting, e.g. by creating hidden bonus tracks or track intros in pre-gaps like it is common habit on commercial CDs. Finally, DAO recording is the only way to write data to the unused R-W sub-channels for e.g. CD-G or CD-TEXT.
Full control over length and contents of pre-gaps (pause areas between tracks). Pre-gaps may be completely omitted, e.g. for dividing live recordings into tracks.
Control over sub-channel data like:
copy, pre-emphasis, 2-/4-channel flags
Support for exact audio, data and mixed mode CD copying.
Support for R-W sub-channel writing.
Tracks may be composed of different audio files supporting non destructive cut.
Accepts WAVE and raw audio files.
CD-TEXT reading and writing with drives that support it.
fmedia is a fast media player/recorder/converter for Windows, macOS, Linux and FreeBSD. It provides smooth playback and recording even if devices are very slow. It’s highly customizable and can be easily extended with additional plugins. Its low CPU & memory consumption saves energy when running on a notebook’s battery.
Play or convert audio files, record new audio tracks from microphone, save songs from Internet radio, and much more! fmedia is free and open-source project, and you can use it as a standalone application or as a library for your own software.
Snd is a sound editor modelled loosely after Emacs. It can be customized and extended using either s7 (included in the Snd sources), Ruby, or Forth. Snd is free; the code is available via anonymous FTP as Snd tarball.
Aften is an audio encoder which generates compressed audio streams based on ATSC A/52 specification. This type of audio is also known as AC-3 or Dolby® Digital and is one of the audio codecs used in DVD-Video content.
Converts PCM source audio into AC-3 audio
Allows for setting of production metadata such as dialogue level, downmix levels, and extended bitstream information
Supports RAW, WAV, AIFF, and CAFF input file formats
Supports single multi-channel or multiple mono source files
Includes several optional pre-processing filters
Uses multi-threading and assembly optimizations to speed up encoding
