W64 to E-AC3 Converter
Processing entirely on your device — large files may take a moment.
Sony Wave64 and Dolby Digital Plus (E-AC3) exist for different jobs: W64 (Sony Wave64) is WAV beyond its 4 GB ceiling — a 64-bit riff on the RIFF container that Sony Vegas and high-resolution field recorders emit for hours-long sessions. Convert audio to E-AC3 for streaming-TV authoring, or E-AC3 tracks to MP3/WAV for editing.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the W64 format
W64 is Sony's Wave64 — what happens when WAV's 32-bit size fields run out of road. A RIFF variant with 64-bit offsets, it shrugs off the 4 GB ceiling that makes plain WAV choke, which is why long field-recording sessions and Sony Vegas projects land in W64.
Inside, it is the same uncompressed PCM as WAV — ffmpeg hands W64 to WAV, FLAC or MP3 without touching a single sample, so conversion is purely about container compatibility.
+Strengths
- ✓No 4 GB size ceiling — hours-long recordings
- ✓Bit-exact PCM, same as WAV inside
- ✓Standard in Sony Vegas workflows
!Limitations
- −Almost nothing outside Sony tools opens it
- −Uncompressed — very large files
- −Legacy niche — new tools prefer RF64
About the E-AC3 format
E-AC3 (Dolby Digital Plus) is the streaming-generation successor of the classic AC3: better audio at roughly half the bitrate, support for up to 15.1 channels, and the mandatory audio codec of UHD Blu-ray and most streaming-TV platforms. Netflix, Amazon and broadcast IPTV all ship it.
For authoring streaming deliverables, E-AC3 at 192-384 kbps is the safe standard. For editing or everyday playback, convert it to WAV/MP3 first — few audio editors accept it natively.
+Strengths
- ✓Better quality than AC3 at half the bitrate
- ✓The streaming-TV and UHD Blu-ray standard
- ✓Up to 15.1 surround channels
!Limitations
- −Poor editor/playback support outside TV pipelines
- −Lossy — not for archival masters
