Shape the sound (Studio voice, audio layers, separate audio files)

Open the Audio tab in the editor. Everything here happens on your Mac: nothing is uploaded, and the recorded files are never changed. Every edit can be undone with ⌘Z.

Record your microphone

Microphone starts on for new recordings. Click its on/off toggle beside the device menu in the capture bar to change it; Slyve remembers your choice. Settings › Recording › Start new recordings with microphone changes the same default.

If Slyve hears no speech on the microphone the first time a project opens, it opens with the microphone muted and says No speech heard with an Unmute button. Slyve keeps your choice for that project and never mutes a take with speech in it.

Choose Allow microphone if permission is missing. Start still records your screen and reports that the microphone was skipped. With no connected microphone, the bar says No microphone and its toggle is off. See Permissions.

Studio voice

Open More at the foot of the Audio card and turn on Studio voice to make speech easier to hear. It shapes the tone, evens out loud and soft words, and softens harsh “s” sounds.

• Tone: Natural (a little more presence), Warm (more body, a softer top) or Clear (more presence and air, for a voice over music).
• Intensity: how much of it you hear, from 0% to 100%. The default is 35%.
• Audition: switch between Original and Processed while the video plays. Both play at the same loudness, so you hear the difference in the sound rather than in the level. The switch only changes what you hear in the editor; the export always uses Studio voice while it is on.

Studio voice works on the microphone, voice-overs and voice layers. It runs after Voice clean-up, and the export uses the same processing as the preview.

Audio layers

Choose Add › Audio layer… to add an audio file that plays with your microphone, for example a voice in another language, a music track or a sound effect. It goes on the Audio layers lane at the playhead; drag it to move it and drag its ends to trim it. Layers can overlap.

Click a layer in the Audio card to set:

• What it is: Voice, Music or Effect. Music under your voice ducks for voices only, and Studio voice shapes voices only.
• Microphone: Mix with mic keeps your microphone audible, or Replace mic silences the microphone while the layer plays.
• Volume.

Each layer has Mute (the export leaves it out too) and Solo. Solo plays that layer, or the Microphone, on its own in the editor while you listen. It is never saved and never changes the export. Click Soloed again to hear everything.

Add › Audio file… still adds a file to the Narration lane, where it replaces the microphone while it plays.

Export separate audio files

In the Export sheet, open Also export and choose Separate audio files. Next to the video, Slyve saves a folder (for example, Demo-stems) containing:

• mic.wav, system.wav, narration.wav, music.wav and effects.wav, for the parts your project has;
• timing.json, which lists where the files start, their length and sample rate, and the edit they follow.

Every file has the video’s edits, including cuts, speed changes and holds. They all start at the same moment and have the same length and number of samples, so they line up with each other and with the video in REAPER, Premiere, Final Cut or Resolve. They are 32-bit float, 48 kHz stereo WAV files.

By default, the files match the video’s mix and add up to it. Once Separate audio files is ticked, a switch appears under it: turn on Audio files as recorded to export the recorded sound with your edits and volumes, but without clean-up, Studio voice, ducking or loudness.
