Release Notes
DrawSplatTM v3.1.19
DrawSplatTM v3.1.19 introduces AudioSplat as a production browser-based multitrack recorder and editor with effects, flexible audio export, optional Google Drive saving and sharing, and its own self-host package.
Classroom Tools
Record, edit, mix, export, and share audio
The release keeps audio local by default while adding an explicit, narrow Google Drive path when a user chooses cloud storage.
Visual editing
Select visible waveform ranges, split, trim, duplicate, delete, zoom long projects, and undo or redo changes.
Effects
Apply fades, amplification, EQ, echo, noise tools, normalization, reverb, silence, and silence truncation to selected audio.
Audio formats
Export MP3 and WAV plus Ogg/Opus, WebM/Opus, and M4A/AAC when the browser supports those encoders.
Google Drive
Authorize only drive.file, save an exported mix privately, and optionally create a share link and Drive preview iframe.
Private by default
Recording, processing, tab-isolated autosave, portable projects, and downloads work locally without an account or backend.
Standalone package
AudioSplat now has its own self-host ZIP and is also included in the full DrawSplat and Tools packages.
Checksums
The release includes SHA256SUMS-v3.1.19.txt for verifying all ZIP downloads.
The package model remains additive: unzip modules into the same web root and keep folder names unchanged. No installer or server-side linking step is required.
Highlights
What changed
Successive Takes
Each new recording can land on a new track automatically, making do-overs and layered narration easier to manage.
Cross-device design
The responsive six-language interface supports current Firefox, Chrome/Chromium, Safari, Android, iOS/iPadOS, Windows, macOS, Linux, and ChromeOS within each browser's media capabilities.
Import and Export
Import common browser-decodable audio files by picker, drag/drop, direct permitted URL, PWA file handling, or supported share targets, then export a mixed audio file.
Sound sources
An alphabetized Sound-Effect Sources menu links to curated libraries while retaining each source's licensing guidance.
Safe cloud choice
Google Drive upload occurs only after an explicit user action, tokens stay in memory, and public sharing remains opt-in.
