❓ Frequently Asked Questions (FAQ)

Q: What is the difference between Peak Gain and RMS Loudness matching? A: Peak gain matching sets the highest audio signal spike to your target dB level, which is ideal for avoiding digital distortion (clipping). RMS (Root Mean Square) loudness matching measures average acoustic power over time, making audio clips sound equally loud to the human ear.

Q: Does this tool re-encode or degrade audio quality? A: No. All gain matching is calculated with 32-bit floating-point precision using Web Audio API and exported as lossless 16-bit uncompressed WAV files.

Q: Are my audio files uploaded to a server? A: No. Apex Club Mix micro-tools operate 100% on the client side. Your audio remains entirely private and processing happens locally inside your browser.

Q: What audio file formats are supported? A: The tool supports all standard audio formats compatible with web browsers, including WAV, MP3, FLAC, AAC, M4A, and OGG.
