Software


a free software, cross-platform digital audio editor and recording application. It is available for Windows, Mac OS X, Linux and BSD.
The latest release of Audacity is 1.3.13, a beta, released on 11 April 2011.

Features and usage 

Audacity can also be used for post-processing of all types of audio, including podcasts by adding effects such as normalization, trimming, and fading in and out. Audacity has also been used to record and mix entire albums, such as by tUnE-yArDs. It is also currently used in the OCR National Level 2 ICT course for the sound creation unit.


Audacity's features:

  • Importing and exporting of WAV, AIFF, MP3 (via the LAME encoder, downloaded separately), Ogg Vorbis, and all file formats supported by libsndfile library. Versions 1.3.2 and later support Free Lossless Audio Codec (FLAC). Version 1.3.6 and later also support additional formats such as WMA, AAC, AMR and AC3 via the optional FFmpeg library.
  • Recording and playing back sounds
  • Editing via Cut, Copy and Paste (with unlimited levels of Undo)
  • Multitrack mixing
  • A large array of digital effects and plug-ins. Additional effects can be written with Nyquist
  • Built-in LADSPA plug-in support. VST support available through an optional VST Enabler.[11]
  • Amplitude envelope editing
  • Noise Removal based on sampling the noise to be removed. Surface noise from records, for example, can be removed with hardly any discernable effect on the music.
  • Audio spectrum analysis using the Fourier transformation algorithm
  • Support for multi-channel modes with sampling rates up to 96 kHz with 32 bits per sample
  • Precise adjustments to the audio's speed while maintaining pitch (Audacity calls it changing tempo), in order to synchronize it with video or run for a predetermined length of time
  • Changes to the audio's pitch without changing the speed
  • Features of modern multi-track audio software including navigation controls, zoom and single track edit, project pane and XY project navigation, non-destructive and destructive effect processing, audio file manipulation (cut, copy, paste)
  • Conversion of cassette tapes or records into digital tracks by automatically splitting the audio source into multiple tracks based on silences in the source material
  • Support for multiple platforms — Audacity works on Windows, Mac OS X, and Unix-like systems (including Linux and BSD), among others
    • The latest stable version supports Windows 98/ME/2000/XP/Vista, but Windows 95 and NT are not supported. Windows 7 support is still provisional. For Windows 7, the developers recommend the latest 1.3.x Beta
  • Audacity uses the wxWidgets software library to provide a similar graphical user interface on several different operating systems.

 

Limitations

A plug-in is required for VST plug-ins in Audacity 1.2.x. Audacity lacks dynamic equalizer controls, real time effects and support for scrubbing. MIDI files can only be displayed.

Only "provisional" support is provided for Windows 7, although the program can be made to run under it with certain known issues, involving launching the application, recording and playback and the interface. Development of the Audacity 1.3 beta series is focusing on providing full Windows 7 support.

Audacity does not currently support WMA, AAC, or most other proprietary or restricted file formats.

 Steinberg Cubase

Cubase is a music software product developed by Steinberg for music recording, arranging and editing as part of a Digital Audio Workstation.

Operation

Cubase creates projects which allow the operator to edit MIDI files, raw audio tracks, and other associated information like lyrics, and to present them in a range of formats including musical scores, editing console, event lists, etc. The operator can also mix the various tracks down into a stereo .wav file ready to be burned onto a CD in Red Book format or .mp3 burnt to CD or DVD as files or to be published on the Web.

While MIDI is a fairly ubiquitous standard for representation of digital music, there is no broadly accepted standard for the interchange of complete projects containing both MIDI and audio between Cubase and other competing recording/editing software (e.g. Logic Pro, Pro Tools, Digital Performer, or Cakewalk), so while actual pure recorded audio information can be exchanged, it is hard to import a whole project (with specific edits, instrument information and automation) in its native format from Cubase to another application and vice versa. The cross-platform OMFI format (which is supported by Cubase SX and newer version) resolves this issue to some extent.
