Want to save an online lecture, a radio stream or your own narration as an audio file? AceThinker Free Audio Recorder captures your PC's sound, your microphone or both, and saves the result as MP3.
Can it record computer sound and microphone input?
The recorder can capture audio playing on the computer, such as a lecture or other playback, and it can record a connected microphone. Choose the audio source that fits the recording: playback, spoken voice, or both sources when you want to include narration alongside computer audio.
How do you start and save a recording?
Start the sound you want to capture, then begin recording in AceThinker. Stop the session when you have the audio you need. Before saving, choose a destination on the computer and an output format; the program stores the resulting file there.
- Start playback before recording computer audio.
- Stop recording when the capture is complete.
- Select where the file will be saved and its format.
Can you organize recordings in the program?
The built-in library lists every recording, where you can rename files and fill in details such as artist, album and cover image. The free recorder runs through a small launcher program that opens from AceThinker's website.
