EZ Sound Recorder records audio from any audio device installed on the system including the Microphone and Line-In.
The program records audio directly to the following formats: CAF, M4A, WAV and ALAC. The program allows the user to set the output format, the quality, the sample-rate, and the number of audio channels to apply on recorded audio files.
Plus all recording controls are automatic so you can record, pause, resume, stop, and the state of the buttons get disabled according to what you are doing so you can't go wrong.
The program is very simple with a real-time audio analysis graphic that brings important visual feedback to the user regarding audio volume and responsiveness. Plus you can customize spectrum colors to your best likes.
