Zap Voicer

# Zap Voicer - Audio as Voice ## What the Extension Does Transforms local audio files (MP3, WAV, and OGG) and audio catalog sound memes into native voice messages on WhatsApp Web. Select an audio file from your computer or search for sounds online, and the extension injects the content directly into WhatsApp’s recording flow, sending it as if it had been recorded through the microphone at that moment. ## Why You Should Install It ### Professional Quality Send voice-overs, recorded replies, music tracks, or pre-produced content with consistent quality and no unwanted background noise. ### Productivity and Speed Record complex messages once and reuse your audio whenever needed. Access the file picker through the button integrated into the message composer or by using dedicated keyboard shortcuts. ### Integrated Sound Library Search for memes, sound effects, and popular audio clips in real time directly from the conversation. Preview sounds before sending them and quickly switch countries to explore global trends. ### Native Experience Recipients receive the content exactly like a voice message recorded through WhatsApp, including native playback-speed controls (1x, 1.5x, and 2x) and continuous playback. ### Customization and Control Configure individual keyboard shortcuts for local files and sound search, enable automatic volume normalization, adjust the silence trimmer, and use an optional artificial delay to simulate natural pauses before sending. ### Privacy and Security All processing takes place locally in your browser. Your files are not uploaded to third-party servers; transmission occurs exclusively through WhatsApp Web’s own infrastructure. ## Key Features - Support for local MP3, WAV, and OGG files with direct bookmarking to Favorites - Integrated audio library with debounced real-time search - Multi-section tabs with fixed dimensions and active visual indicators - Collapsible vertical menu with country selection for trends - Audio preview button (play/pause) with secure decoding through Blob URLs - Configurable silence trimmer with adjustable sensitivity threshold and breathing margin - Zero-latency instantaneous audio stream injection for immediate transmission - Unified action button in the message composer with quick opening and keyboard shortcuts - Customizable keyboard shortcuts (Alt+A for local files and Alt+M for sound search) - Interactive visual tips (Coach Marks) with dark spotlight focus and intelligent speech balloons - Settings gear icon in the sound library header for instant access to extension options - Synchronized visual tips reset button in options with real-time tab updates - Forensic technical diagnostic system with one-click JSON report export covering audio, system, and WhatsApp Web compatibility - Direct access to the settings page by clicking the extension icon in the browser - Animated one-time modal presenting the latest version updates - Intelligent volume normalization using the Web Audio API - Hands-Free recording simulation integrated into the original interface - Manual cancellation with immediate audio interruption - Dynamic support for WhatsApp Web’s Light and Dark themes Designed for everyday messaging, providing seamless voice audio playback directly into WhatsApp Web conversations. --- ## Release Notes ### Version 1.4.4 - More compatible microphone and send detection across WhatsApp Web languages and interface changes, with a shared resolver for automation and diagnostics. - Fixed false control matches, added support for nested buttons and asynchronous rendering, and prevented duplicate actions. - Shared audio preparation with independent streams per consumer prevents preliminary capture from stopping the main recording. - Improved recording/playback synchronization to reduce missing audio beginnings, with silence and invalid-sample checks at the source and injected stream. - Notifications distinguish sending initiated, confirmation observed in the interface, errors and timeouts. - Expanded JSON diagnostics with per-attempt stages, settings, signal metrics, audio consumers, interceptor integrity and message-state timelines. - Technical page and script-resource inventory with sanitization; optional extension list with browser permission. - Fixed hardcoded Portuguese in toasts, dialogs, history, accessibility labels and errors.
