Reaper, un clon del Vegas de Sony, al menos en la interfaz gráfica. Es gratuito mientras dure la fase beta, hasta la v1.0. Realmente impresionante lista de características:
Basic features:
Support for an unlimited number of audio tracks.
Audio tracks are all fully routable (multiple inputs, outputs).
Volume, pan controls and envelopes per track.
Supports audio processing plug-ins (DirectX, DXi, VST, VSTi, and Jesusonic) with automation, easy chain manipulation and editing.
Pitch shifting and time stretching.
Fast, reasonable and usable Windows-style UI, working well on both low and high resolutions or multiple monitors.
ASIO, Kernel Streaming, WaveOut, and DirectSound support for playback and recording.
Reads WAV, OGG, MP3 and MIDI files, records WAV and MIDI files.
Can render to WAV, OGG, MP3 if lame is installed.
Full SMP support (can utilize 2 or more processors).
Multi-layer undo/redo support.
User creatable color themes.
Advanced features:
Unlimited send/receives per track, with configurable parameters (pre-fx, post-fx, volume/pan adjustment/envelopes, mix to mono, phase, etc.).
Any track can act as a bus, for routing flexibility.
Tracks can have one or more (mono or stereo) hardware sends, for analog mixing capability.
Fully routable/FX-able folder tracks that can contain group tracks.
Item grouping.
Ripple editing.
Grid/snap support with configurable options.
Markers.
Unlimited takes per media item.
Auto punch-in/punch-out functionality.
Automatic record monitoring modes.
Selection length granularity options as well as grid snapping.
Tempo envelope (for grid lines/snapping/ruler), play-speed envelope.
Project consolidation/export options (for rendering all or parts of any number of tracks to WAV, etc.).
A UI and architecture that allows you to easily cut loops of many tracks simultaneously, without having to write them to disk.
Support for plug-in generated media (such as click tracks, etc.).
Project tempo envelopes for variable tempos in track, grid/snapping that supports variable tempos.
64-bit floating point sample pipeline for high quality.
Advanced recording and monitoring options; examples:
You can route multiple tracks (inputs and/or media items) into a bus, and record THAT mixed down version.
You can record the input signal, or record the post-FX, post-track-render signal.
You can switch recording sources on the fly, even while recording.
You can arm/disarm tracks' inputs while playing or recording.
Other features:
Human readable, human editable, backwards and forwards compatible project file format.
Options to build peaks for recorded files on the fly.
Lots of control for the user to specify where recorded files go, etc., when dealing with many projects.
Template support to make it easy to load a project template and save it as a new project when you begin.
Input/output channel name aliasing (why view your inputs as "MOTU 896: Analog 1" when you could have them be "Vocal Mic", etc.).
Options for automatically backing up project files to alternate paths, time-stamped versions, etc.
Things planned for REAPER v1.0 (coming mid 2006) that are not in this release:
More annotations.
More fade shapes.
More envelope shapes.
Regions.
MIDI editing and more MIDI functionality.
Higher quality resampling modes.
Public plug-in API.
Better control surface support.
MBCS filename compatibility.
