A voice note with no installation
Open the online voice recorder, choose a microphone and allow access when you are ready. Record, pause, trim and download a WAV. Audio is handled locally in the browser.
The browser tool has a 20-minute cap and records one microphone source. It is not the desktop speaker recorder or multitrack editor.
Computer audio or narration alongside it
Use Free Sound Recorder for Windows. Select the playback device carrying the computer sound. Add your microphone when narration belongs in the same take.
After Stop, the source recordings are separate tracks. You can balance the voice and background before exporting one mixed audio file.
Several devices and a session to revisit
Select the available devices you need, make a test and record them together. Device availability and performance depend on hardware and Windows drivers.
Save an .amss session when the separate tracks matter. Export MP3, WAV or FLAC when you need the current mix for listening or sharing.
