Choose the video’s output
Open the video in your browser or player and check its speaker or headphone output. Select that playback source in Free Sound Recorder. Leave microphones unchecked for a soundtrack-only take.
Other sound using the same device can be included. Quiet notifications and unrelated players before recording.
Record the part you need
Press Record, play the part you are allowed to capture, then Stop. Listen to a short test before making a longer take. Playback restrictions or exclusive audio paths can affect whether capture is available.
To add spoken commentary, select your microphone too. The selected sources are kept on separate tracks when the recording stops.
Trim, balance and export
Remove an unwanted beginning or ending. Balance any narration against the computer sound, then export the current mix as MP3, WAV or FLAC.
Save an .amss session if you want to keep the source tracks editable rather than only the finished mix.
