📖 User Manual: How to Convert Audio Bit Depth

1. 📂 Select Your Audio FileDrag and drop your audio file (WAV, MP3, FLAC, OGG, or AAC) into the drop zone, or click to browse from your computer.
2. 🎛️ Choose Target Bit DepthSelect your preferred output resolution:
   • 16-bit PCM: Standard CD quality, optimal for distribution and streaming platforms.
   • 24-bit PCM: High-resolution studio master quality for mixing and archival.
   • 32-bit Float: Maximum dynamic range headroom for heavy DSP processing.
3. 🎚️ Select Dithering ModeChoose Triangular (TPDF) when downsizing bit depth (e.g., 24-bit to 16-bit) to eliminate quantization noise, or None if keeping or increasing resolution.
4. 🚀 Convert & DownloadClick Convert and Download WAV. Your file will be processed in real-time in your browser and automatically downloaded as an uncompressed WAV file.

❓ Frequently Asked Questions (FAQ)

Q: What is audio bit depth?

💡 A: Bit depth determines the dynamic range and noise floor of an digital audio signal. Higher bit depths (like 24-bit or 32-bit float) capture quieter details with lower background noise and greater headroom.

Q: Why should I convert 24-bit audio to 16-bit?

💡 A: While 24-bit is preferred during recording and mixing, 16-bit / 44.1 kHz remains the standard for Red Book audio CDs and certain legacy audio players.

Q: What is Dithering and when should I use TPDF?

💡 A: Dithering adds subtle, controlled low-level noise when truncating audio from a higher bit depth to a lower one (e.g., 24-bit to 16-bit). It replaces harsh quantization distortion with smooth, natural background noise. Triangular (TPDF) is the industry-standard choice.

Q: Does converting 16-bit audio to 24-bit improve sound quality?

💡 A: No. Upscaling 16-bit audio to 24-bit adds extra bit space (headroom), but it cannot recover detail or dynamic range that was not present in the original source file.

Q: Are my audio files uploaded to a server?

🔒 A: No! All processing is executed locally in your browser using Web Audio API offline context. Your audio files never leave your computer.
