Frequently Asked Questions (FAQ)
Yes! You can upload disparate audio formats simultaneously; the browser-based engine automatically harmonizes them into a unified, high-quality audio file.
It is the audio bitrate—how much data is stored per second of sound. Higher values sound better but make larger files and take longer to merge. Speech and lectures work well at 128kbps; music is usually fine at 192–320kbps. The default is 128kbps.
No. The system decodes and merges your sound files locally using high-fidelity parameters, ensuring original dynamic range and frequency spectrums are preserved.
Never. All merging operations run 100% locally inside your client browser sandbox (on-device), guaranteeing total conversational confidentiality.
