Mixcraft allows you to make mixes of music, different sounds and add effects from multiple audio tracks. The program supports many audio formats: MP3, OGG and WMA files and allows import files in WAV, AIF, OGG, WMA and MP3. Among the features, it is possible to record multiple MIDI or audio tracks simultaneously, to include many effects (more than 18 proposed), burn CDs of their mixes in just one click and more. It has a simple and friendly interface (with colors and smart navigation), allowing access to most used functions easily.
The software is not free but its price is reasonable when compared to products such as Sound Forge and a little more comprehensive than the free software Audacity. It runs on most Windows operating systems, requires a minimum of 512 MB of RAM (2GB recommended), and 1.0 Ghz CPU (2 GHz recommended) and a sound card.
