BestPractice

BestPractice is a musician's practice tool, to slow down or speed up music, either from an MP3 file or directly from a CD. Ordinarily the sound is distorted when slowed down our sped up - you get the effect like when playing a 33 rpm record on 45 rpm speed (remember the Chipmunks?). BestPractice tries to correct this, so you can slow down and speed up music, while keeping the original pitch. It is also possible to change the pitch of the music without affecting its tempo. Play along with for instance Eb tuned guitars without retuning your own, or slow down that high-speed guitar solo on a CD that you like to learn.

Max

Max is an application for creating high-quality audio files in various formats, from compact discs or files. When extracting audio from compact discs, Max offers the maximum in flexibility to ensure the true sound of your CD is faithfully extracted. For pristine discs, Max offers a high-speed ripper with no error correction. For damaged discs, Max can either use its built-in comparison ripper (for drives that cache audio) or the error-correcting power of cdparanoia.

Once the audio is extracted, Max can generate audio in over 20 compressed and uncompressed formats including MP3, Ogg Vorbis, FLAC, AAC, Apple Lossless, Monkey's Audio, WavPack, Speex, AIFF, and WAVE. If you would like to convert your audio from one format to another, Max can read and write audio files in over 20 compressed and uncompressed formats at almost all sample rates and and in most sample sizes. For many popular formats the artist and album metadata is transferred seamlessly between the old and new files. Max can even split a single audio file into multiple tracks using a cue sheet.

Max leverages open source components and the resources of Mac OS X to provide extremely high-quality output. For example, MP3 encoding is accomplished with LAME, Ogg Vorbis encoding with aoTuV, FLAC encoding with libFLAC, and AAC and Apple Lossless encoding with Core Audio. Many PCM conversions are also possible using Core Audio and libsndfile. Max is integrated with MusicBrainz to permit automatic retrieval of compact disc information. For MP3, FLAC, Ogg FLAC, Ogg Vorbis, Monkey's Audio, WavPack, AAC and Apple Lossless files Max will write this metadata to the output.

Max allows full control over where output files are placed and what they are named. If desired, Max will even add the encoded files to your iTunes library in a playlist of your choice. For advanced users, Max allows control over how many threads are used for encoding, what type of error correction is used for audio extraction, and what parameters are used for each of the various encoders. Max is free software released under the GNU General Public License (GPL).

MAD: MPEG Audio Decoder

MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 and the MPEG-2 extension to lower sampling frequencies, as well as the de facto MPEG 2.5 format. All three audio layers — Layer I, Layer II, and Layer III (i.e. MP3) — are fully implemented.

MAD does not yet support MPEG-2 multichannel audio (although it should be backward compatible with such streams) nor does it currently support AAC.

MAD has the following special features:

• 24-bit PCM output
• 100% fixed-point (integer) computation
• completely new implementation based on the ISO/IEC standards
• available under the terms of the GNU General Public License (GPL)

Because MAD provides full 24-bit PCM output, applications using MAD are able to produce exceptionally high quality audio. Even when the output device supports only 16-bit PCM, applications can use the extra resolution to increase the audible dynamic range through the use of dithering or noise shaping.

Because MAD uses integer computation rather than floating point, it is well suited for architectures without a floating point unit. All calculations are performed with a 32-bit fixed-point integer representation.

Because MAD is a new implementation of the ISO/IEC standards, it is unencumbered by the errors of other implementations. MAD is not a derivation of the ISO reference source or any other code. Considerable effort has been expended to ensure a correct implementation, even in cases where the standards are ambiguous or misleading.

Because MAD is available under the terms of the GPL, it can be freely used in other GPL software, and is also available for immediate evaluation prior to obtaining a commercial license.

CDRDAO

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.

Features

• 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
• 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.
• CDDB access to automatically create CD-TEXT data.
• Support for on-the-fly copying.

MediaPortal

MediaPortal is an Open Source application ideal for turning your PC in a very advanced Multi-Media Center / HTPC. MediaPortal allows you to listen to your favorite music & radio, watch your video's and DVD's, view, schedule and record live TV and much more.

As Open Source software licensed under the GNU/GPL agreement, you get MediaPortal for free. This means anyone can contribute to MediaPortal or customize for their own needs!

MediaPortal is built on the Microsoft .NET framework using C# and currently has a growing international community of over 60,000 users.
History

MediaPortal's roots lie in the XBox Media Center (XBMC) project which goal was to build a media center application for the Microsoft XBox gaming console. Erwin Beckers (also known as Frodo) concluded early in the XBMC project that there were notable limitations to the xbox platform, mainly that it is unable to support TV cards. XBox Platform limitations like these would ultimately hinder the vision of a feature rich media center application.

In February 2004, Erwin left the Xbox Media Center project to start a new project, now known as MediaPortal that would run on the Microsoft Windows platform. Initially existing code was re-used from the XBMC project but after several releases and innumerable feature enhancements there has been almost a complete re-design.

Today, MediaPortal continues as an open source project, has a core team of developers and a growing community of over 60,000 registered users.

In 2006 MediaPortal enters a new aera with the release of the TV server. For the first time users can now use multiple frontends for viewing & recording TV streamed from 1 or more TV servers.

LAME

LAME is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL. LAME is considered the best MP3 encoder at mid-high bitrates and at VBR, mostly thanks to the dedicated work of its developers and the open source licensing model that allowed the project to tap into engineering resources from all around the world. Both quality and speed improvements are still happening, probably making LAME the only MP3 encoder still being actively developed.

Following the great history of GNU naming, LAME originally stood for LAME Ain't an Mp3 Encoder. LAME started life as a GPL'd patch against the dist10 ISO demonstration source, and thus was incapable of producing an mp3 stream or even being compiled by itself. But in May 2000, the last remnants of the ISO source code were replaced, and now LAME is the source code for a fully LGPL'd MP3 encoder, with speed and quality to rival and often surpass all commercial competitors.

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to use the open source model to improve the psycho acoustics, noise shaping and speed of MP3. LAME is not for everyone - it is distributed as source code only and requires the ability to use a C compiler. However, many popular ripping and encoding programs include the LAME encoding engine, see: Software which uses LAME.

Using the LAME encoding engine (or other mp3 encoding technology) in your software may require a patent license in some countries.

LAME features:

• Many improvements in quality in speed over ISO reference software. See history.
• MPEG1,2 and 2.5 layer III encoding.
• CBR (constant bitrate) and two types of variable bitrate, VBR and ABR.
• Encoding engine can be compiled as a shared library (Linux/UNIX), DLL , Directshow filter or ACM codec (Windows).
• Free format encoding and decoding.
• GPSYCHO: a GPL'd psycho acoustic and noise shaping model.
• Powerful and easy to use presets.

MP3Gain

MP3Gain analyzes and adjusts mp3 files so that they have the same volume. MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.

AC3Filter

AC3Filter is a high quality free audio decoder and processor filter. It allows media players to playback movies with AC3 and DTS audio tracks. Also it can process any audio track, much of processing options allows to adjust the sound in almost any way. It is possible to upmix any audio source to 6 channels. Filter can do multi-channel and digital (SPDIF) output. It can encode any audio source to AC3 on-the-fly and send it over SPDIF to the receiver.

Playback:

• Watch movies with AC3 and DTS audio tracks
• Listen multi-channel (AC3/DTS) AudioCD
• Playback WAV files with AC3/DTS content, ripped from multi-channel AudioCD without any conversion of these files.
• Playback raw .AC3 and DTS files (with help of AC3File filter)

Process:

• Up-mix any audio track (even plain stereo) up to 6 channels
• Down-mix any audio track to any number of channels (to match your speaker configuration)
• If you have an external Dolby ProLogic decoder, you may use ProLogic down-mix to help DPL decoder to extract surround information
• Watch movies under poor hearing conditions (noisy environment, weak speakers, ...)
• Decrease dynamic range to watch movies at night
• Apply time shift to the audio track to synchronize audio with video.
• Adjust gain of every input/output channel independently to compensate loudness differences
• Adjust time delays for every channel to compensate different distances to loudspeakers.

SPDIF output:

• Passthrough AC3 and DTS over SPDIF without any change to external decoder
• Encode any audio to AC3 and transmit it over SPDIF
• USB sound cards supported

CDex

CDex can extract the data directly (digital) from an Audio CD, which is generally called a CD Ripper or a CDDA utility. The resulting audio file can be a plain WAV file (useful for making compilation audio CDs) or the ripped audio data can be compressed using an audio encoder. Many encoders are supported, to name a few:

• Lame MP3 encoder
• Internal MP2 encoder
• APE lossles audio format
• Ogg Vorbis encoder
• The Windows MP3 encoder (Fraunhofer MP3 encoder)
• NTT VQF encoder
• FAAC encoder
• Windows WMA8 encoder

In addition, WAV files on the hard drive can be converted to a Compressed Audio File (and visa versa). CDex also supports many audio file tag formats like the ID3V1 and ID3V2 tags, which can be automatically inserted as part of the ripping process.

Feature List

• Direct recording of multiple tracks
• Read / store album information from/to the cdplayer.ini file
• Read / store album information from/to a local and/or remote CD Database (CDDB)
• Support CD-Text (if your CD-drive supports it)
• Advanced jitter correction (based on the cd-paranoia ripping library)
• Indicates track progress and jitter control
• Normalization of audio signal
• Supports many CD-Drive from many manufacters
• Conversion of external WAV files
• Support for M3U and PLS play list files
• Best of all, it's free (GPL license, source code available)
• Serveral languages are supported
