Record the sound you actually need
Select a microphone, a playback source or several available sources in Free Sound Recorder. Adjust each input’s gain and make a short recording to check the levels.
Press Stop when the take is complete. The selected sources appear as separate tracks, so a quiet microphone can be adjusted without changing the other source recordings.
Prepare the mix
Trim unwanted sections and balance track volume. Mute tracks you do not want to include, or use Solo while checking one source. Listen to the mix before you export.
Export MP3 and keep an editable copy
Choose MP3 in Export / Download and select a bitrate for the output. The current release offers 128, 192 and 256 kbps MP3 choices. The export is the current audible mix.
Save an .amss session as well if you want to return to the separate tracks. WAV and FLAC are available when another editing or lossless workflow fits better.
