Alternate Quick Audio - A simple program for converting audio files. The program is freeware. It allows the converting of audio files (some video file formats, too) into other audio formats (E.g. from WAV to MP3 or MP4 to WAV).
The following formats are supported by the built-in audio converter: WAV, MP3, OGG, AAC, AIF, ASF, AST, AU, FLAC, FLV, M4A, MP2, MP4, MPG, RA, SF, VOC and WMA. The program requires the .NET-framework 2.0 (already included in operation system since Windows Vista).
