How to merge hundreds of audio files without crashing a browser
Prepare, validate and stream a large ordered folder into one WAV or RF64 file.
Step by step
- Put tracks in one folder with sortable names.
- Choose the complete folder and review the order.
- Choose a destination and let the preflight identify unreadable tracks.
Why the old approach fails
Decoding hundreds of compressed tracks and building one giant in-memory buffer can use several times the source size. A single corrupt or browser-unsupported MP3 can also abort the whole batch unless files are validated independently.
WAV versus RF64
Classic WAV uses 32-bit size fields and is normally limited near 4 GB. RF64 uses 64-bit size information while preserving a WAV-style structure. Very long output may require an editor that explicitly supports RF64.
Compatibility checklist
Keep free disk space above the estimated uncompressed output, prevent the computer from sleeping, use consistent sample rates where possible and listen at file boundaries afterward. Browser decoders vary, so replace a named unreadable track with a standard PCM WAV when necessary.
