Introduction
Until recently, serious multitrack audio production required expensive desktop workstations like Pro Tools, Ableton Live, or Logic Pro. Browser-based tools were limited to basic single-track trimming.
With ToolBuddy's Digital Audio Workstation, creators can now produce, arrange, automate, and mix complex multitrack sessions directly inside any modern web browser.
The 4-quadrant interface layout
ToolBuddy's workspace is organized into four purpose-built areas: the Top Header and Transport bar containing playback controls, BPM timer, and the 6-tool palette; the Left Project Dock managing tracks and media assets; the Center Timeline Canvas rendering interactive waveforms at 60 FPS; and the Right Inspector providing granular track and effect controls.
Click the floating 'Fullscreen' button in the upper-right corner to expand the workstation into an immersive studio mode that eliminates browser distractions.
Clip arrangement and non-destructive fades
Drag audio clips along or across tracks to arrange your song structure. Hover over the top-left or top-right corners of any clip to reveal interactive fade handles. Dragging inward creates smooth exponential fades that prevent harsh clicks.
Overlapping two clips automatically creates an equal-power crossfade, making transitions between musical sections or dialogue lines seamless.
Vector automation lanes for dynamic mixing
Click the '📈 Auto' button in the toolbar to reveal vector automation lanes beneath each track. You can draw volume swells, panning sweeps, or filter cutoff curves over time.
Keyframes support both linear and smooth Bezier curve interpolation, giving you professional dynamic control over your mix.
