.NET researching application for rendering, recording, playback, analyzing and compression of audio data.

The Sound Editor app is intended for users who wants to explore audio signals through visual sound analysis. Also this program can be used in the ip-telephony since it allows compress and decompress audio data to G.711 codec using two main companding algorithms, the µ-law algorithm and A-law algorithm. The app works only with .mp3 and .wav files.

• you can easily playback, pause and rewind music or speech like in audio player
• you can visualize audio signals in 3 ways:
• wave viewer
• spectrum viewer
• spectrogram viewer
• you can record audio from microphone for further analysis
• you can compress and decompress audio data with G.711 codec or using simple resampling.

To switch representation of the spectrum use Left button click and Right button click. To record your own audio file you need to create empty .wav file, select available microphone from the list then select the newly created file and start the recording.
