Mp3 Audio Editor is a powerful software tool that allows you to edit audio files, apply effects to them, convert and mix them, and much more. The program can edit audio files of all popular formats, such as MP3, WAV, WMA, Ogg, etc. Besides, it can record sounds from your microphone or PC and extract the tracks of audio CDs.
Mp3 Audio Editor offers a really large number of functions and tools to help you acquire audio streams from all the possible sources and edit them. To mention some, the program allows you to extract the audio from your video files, download online videos from YouTube in batches, and – optionally – extract their audio, rip audio CDs, and create new blank audio streams to start from scratch. A very novel and helpful feature of Mp3 Audio Editor is the speech synthesizer, which allows you to create an audio stream from a block of text via a synthetic voice.
Despite the amount of functions the program comprises, it features a modest and a bit uncolored user interface that includes a comprehensive command ribbon in the style of the MS Office 2007/2010 applications. Three of those ribbons are Edit, Effect, and Noise Reduction that offer you quick access to most of the editing functions included. Once you open an audio file or recording, the program shows it to you as a waveform graph, and then allows you to select a portion or all of it to work with. You can cut/copy/paste audio portions, delete, crop, repeat, mix, and silence your selection, or fade it in and out. Finally, you can also reduce different kinds of background noises, such as the cassette noise or the voice breath.
In short, Mp3 Audio Editor is a powerful and comprehensive program that includes all the extra tools you will probably ever need to edit your audio files. Considering the amount and the quality of the offered tools and functions, I would say that the program's price is quite reasonable.
