⚙️ Web Audio API PCM Waveform Slicing & Zero-Crossing Envelope Shaping

Installing heavy Digital Audio Workstations (DAWs) just to trim silence off a voice memo or extract a 30-second song hook is overkill, while cloud MP3 cutters waste bandwidth uploading huge audio files.

DH Tools decodes audio streams into 32-bit floating-point stereo PCM buffers inside your browser, renders a high-precision canvas waveform, applies optional linear gain envelopes (Fade-In / Fade-Out), and compiles the sliced buffer instantaneously.

❓ Frequently Asked Questions

We use the browser's native Web Audio API (`AudioContext.decodeAudioData`) to decode your audio into PCM samples in local RAM, slice the exact millisecond range, and export directly to your device.
Standard smartphone ringtones should be trimmed between 20 and 30 seconds. Enable a 1-second Fade-In so the ringtone builds smoothly.
Cutting a loud chorus mid-beat can sound abrupt or cause a tiny speaker pop. A short fade creates a polished, radio-ready transition.
