Spectro is a freeware audio file analyzer for Windows. Currently capable of reading FLAC, APE, MP3 and WAV files. Spectro lets you view vital data about compressed audio files and creates a spectrogram of the wave data. This allows you to quickly and easily spot quality issues with a file and also look for transcodes.
fre:ac is a free open source audio converter and CD ripper with support for various popular formats and encoders. It currently converts between mp3, MP4/M4A, WMA, Ogg Vorbis, FLAC, AAC, WAV and Bonk formats.
With fre:ac you can easily rip your audio CDs to MP3 or WMA files for use with your hardware player, or convert files that do not play with other audio software. You can even convert whole music libraries retaining the folder and filename structure.
The integrated CD ripper supports the CDDB/freedb online CD database. It will automatically query song information and write it to ID3v2 or other title information tags.
BatchEncoder is an audio files conversion software. It supports most of popular audio file formats including lossy and lossless compression. The program is very simple to use. BatchEncoder is basically GUI front-end for command-line tools. All it does is create background processes and pass arguments to it with options set in presets/format menu and additionally adds input and output file paths.
EAC is often used to create an exact copy of a CD which can be stored in a digital media archive or library. The goal is to preserve all information from a CD, such that the CD can be recreated from an archive and or is playable from a library. With EAC, the original audio files and a .cue file, an exact copy can be made; and with FLAC files, a lossless music library may be built. Creating an individual folder which contains the album’s compressed audio files and a cue file is done via the following method:
Open EAC and select the FLAC encoder
Insert the CD you wish to archive
If using the freedb plugin, select the correct cover art
Verify that the downloaded information is complete and correct
Convert all CD information to title case
Remove any extra spaces
Detect the CD’s gaps
Create the cue sheet and album folders
Rip the CD in Burst Mode, which creates the individual audio files
Switch to Secure Mode and re-rip tracks any tracks that did not rip accurately
This process also creates an EAC log file in the same folder.
Mp3tag is a powerful and easy-to-use tool used to edit the metadata of audio files. It supports batch tag-editing of ID3v1, ID3v2.3, ID3v2.4, iTunes MP4, WMA, Vorbis Comments and APE tags for multiple files at once, covering a variety of audio formats.
Furthermore, it supports online database lookups from Amazon, Discogs, MusicBrainz or freedb allowing you to automatically gather proper tags and download cover art for your music library.
You can rename files based on tag information, replace characters or words in tags and filenames, import / export tag information, create playlists and more.
FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo just like you would an MP3 file.
FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.
