    Guide 11.7

    Settings: Audio

    Intermediate, 3 min read. Checked with Scalpel 1.12.8 on October 15, 2026.

    In short

    The Audio tab has four controls: Enable audio (the master switch), Sound effects, Voice callouts and Volume (80% by default, in 5% steps). All three switches are on by default. Switching off Enable audio silences everything, tape sound included. Tape sound itself is switched on in the Level 2 panel's cog, not here.

    Scalpel talks so you can keep your eyes on the book: "Filled", "Out, in profit", "Stopped out". Open Settings (Ctrl+,) and pick Audio.

    The Audio tab at its defaults: everything on, volume 80%.

    Every option

    OptionWhat it does for your tradingDefaultAllowed valuesWhen to change it
    Enable audioThe master switch. Off silences callouts, sound effects and tape sound.OnOn or offOff when you need silence, for a call or a screen recording.
    Sound effectsShort sounds: order sent, fills, rejections, alerts, the settings-saved chime. Tape sound also needs this on.OnOn or offOff if you want words only (and no tape sound).
    Voice calloutsSpoken confirmations: entries, fills per preset, scale-outs, "Out, in profit" or "Out, at a loss", stop-outs, take-profits, breakeven, trailing, rejections, connection changes, SIM and LIVE switches, the risk lock, session times, the bull trap and thin bid exit warnings, and scanner alerts.OnOn or offOff if you prefer sounds only. An event that has both a voice and a sound plays the sound instead.
    VolumeHow loud callouts and sound effects play.80%0% to 100%, in 5% stepsSet it against your music or news. 0% silences everything, tape sound included.

    The note reads: "Sound effects and voice can be muted independently. Master mutes both."

    How the callouts behave

    • Voice wins over sound. When an event has both a callout and a sound effect, only the voice plays while voice is on. Turn voice off and you hear the sound instead, never both.
    • No talking over each other. A callout that arrives while another is speaking is dropped, so two callouts never garble. The full list of what Scalpel says is in guide 10.1.
    • Scanner announcements only come from scan panels that are open on a desk; mute a panel with its bell.
    • Apply plays a chime, using the new settings, so you hear at once whether sound is on.

    Tape sound is somewhere else

    Tape sound, inspired by Aggr.trade, plays the focused desk's prints as notes, buys high in the right ear and sells low in the left, so you can hear the flow while your eyes stay on the book. It has its own switch, volume and thresholds in the Level 2 panel's cog, under the tape sound settings. It plays only while Enable audio and Sound effects are both on here, but this tab's Volume does not set its level: the cog's volume does. See guide 3.4.

    Tip

    Want the tape but not the chatter? Leave Enable audio and Sound effects on, switch Voice callouts off, and turn tape sound on in the Level 2 cog.

    What can go wrong

    • Nothing plays. Check Enable audio, then Volume above 0%, then your computer's own output device. Audio plays on Windows and macOS. See No callouts or tape sound.
    • A callout was skipped. Another was still speaking. That is by design.

    Questions

    How do I turn off Scalpel's voice?
    Untick Voice callouts on the Audio tab and click Apply. Sound effects keep playing, and events that have both play the sound instead.
    Why can't I hear the tape sound?
    Tape sound is switched on in the Level 2 panel's cog, and it also needs Enable audio and Sound effects on in Settings > Audio. A Volume of 0% here silences it too.
    Does Volume change the tape sound?
    No. The tape has its own volume in the Level 2 cog. Only 0% here, or switching off Enable audio or Sound effects, silences it.
    Can two callouts play at once?
    No. A new callout is dropped while one is speaking, so they never overlap.
