It provides an extensive set of features, but is a very small and lightweight application (the installer is less than 1 megabyte, and includes many effects and a sample project). REAPER supports ASIO, Kernel Streaming, WaveOut, and DirectSound for playback and recording. It reads WAV, OGG, and MP3 files, and records WAV files. You can arrange any number of items in any number of tracks and use audio processing plug-ins (DirectX and Jesusonic). REAPER also supports volume, pan controls and envelopes per track, multi-layer undo/redo, and user creatable color theme
Key features Cockos Reaper
• By a huge plus of the program is that it supports VST-hosts 2 and 3, not counting support DirectX plug-ins or RTAS.
• You can use a built-in editing audio or MIDI tracks, as well as third-party plug-ins.
• The program also supports the connection of virtual instruments ReWire.
• Thanks to the harmonious interface, you can always see what you are editing at the moment.
• A virtual multi-channel remote control is always in front of your eyes - with it you can immediately perform operations with a change in volume, editing effects such as through any given track, and the Master-track.
After all, if you record the audio material directly from the input sound card or microphone in your possession is a virtual audio editor, which, if anything, makes it easy to change the recorded track.
When you install the software automatically chooses the optimal settings for your operating system and sound card. The only thing you need to do - is to select the settings for the sound that you want to use.
If a driver ASIO4ALL, the optimal response time for a response program when a key is pressed on a MIDI keyboard, an average of 512 samples, ie 10 m / sec.
Polyphony is not limited to, all will depend on how powerful a computer you use. Here, of course, plays the role of processor speed and memory, as the saying goes, the more the better. If you do not like built-in audio editor, the settings you can set a reference to any external program for editing sound.
For all that is not Reaper is a great place on the hard drive and not load the processor, as the program of a series of FL Studio, Cubase, Reason or Sonar. With this software you can run even on low-powered computers with sound cards that do not support modes Full duplex. Although, if saundkarta supports this mode, you get unlimited opportunities to create their own compositions with a professional sound, even in such formats as 5 +1, but with additional plug-ins, and 7 +1.
REAPER is a digital audio workstation: a complete multitrack audio and MIDI recording, editing, processing, mixing, and mastering environment. Using your current computer and no other software, you can import any audio and MIDI, synthesize, sample, compose, arrange, edit, mix, and master songs or any other audio projects. If you add a hardware audio interface of your choice (AD / DA: analog-to-digital/digital-to-analog) and a microphone, you have a complete recording studio, suitable for recording anything from a soloist to a band to an orchestra (even if the orchestra is just you).
