PolderbitS Sound Recorder and Editor allows you to convert cassette tape, video, and vinyl LP recordings into mp3 and WAV files. It features several filters to improve the sound quality of your recordings, clean vinyl records, and remove noise from cassette tapes. Once PolderbitS digitizes your recordings, you can burn the tracks onto CD using your CD burner and CD burner software, or save the music to listen on your MP3 player or play it from your PC.
PolderbitS can be used for all your digital audio editing and recording tasks, including converting your files from mp3 to wav, or converting wav files back to mp3. You can also edit your existing mp3 or wav files by splitting recordings into multiple tracks or fading in and out or cutting out fragments of sound from within the middle of a track.
