How to Convert HEVC to WAV Online
- Upload Your HEVC Files: Drag and drop or click "Add Files" to select one or more
.hevc,.h265, or.movfiles containing HEVC video. Batch is supported — every file is processed on our servers session. - Pick a Quality Preset: Default is "Very High (Recommended)". Highest produces the largest WAV with maximum decode fidelity; Lowest trades headroom for the smallest file. Because WAV is uncompressed PCM, the preset mainly affects the decoder pipeline, not the output container.
- Set Audio Channel and Sample Rate (Optional): Audio Channel defaults to Original — change to Mono for voice/podcast work or Stereo to force a two-channel mix. Audio Sample Rate defaults to Original; pick 44100 Hz to match CD audio, 48000 Hz to match the iPhone source rate, or down-sample to 16000 Hz / 8000 Hz for speech-recognition input.
- Trim and Convert (Optional): Enter a start time and duration (seconds or HH:MM:SS.sss) to extract only the segment you need. Click Convert and your WAV files download to your device — no sign-up, no watermark, no sign-up.
Why Convert HEVC to WAV?
HEVC (High Efficiency Video Coding, also called H.265) became the default capture codec on iPhone 7 and later when iOS 11 shipped on September 19, 2017. Inside almost every HEVC file you'll find an AAC-LC audio track at 48 kHz stereo, though Blu-ray rips and some camcorder masters carry AC-3 (Dolby Digital) instead. WAV stores audio as raw uncompressed PCM, which is why every digital audio workstation, transcription engine, and broadcast tool accepts it as a first-class input. Extracting the audio to WAV does not "upgrade" lossy AAC to lossless — it simply repackages the decoded samples without further encoding loss.
- DAW imports without re-encoding — Audacity, Pro Tools, Logic Pro, Reaper, and Adobe Audition all accept WAV as a native format, so editors don't pay a quality penalty on every save.
- Transcription and ASR pipelines — Whisper, AssemblyAI, Rev, and Otter all prefer WAV at 16000 Hz mono; pick those settings here and skip a pre-processing step.
- Podcast and interview workflows — Pull dialogue from an iPhone HEVC field recording into your podcast project at 48 kHz stereo, the standard rate for video-paired audio.
- Archival masters — Once you've cut a final mix, a WAV bounce is the safest archival format: no codec rot, no patent licensing, readable by tools written in 1995 and tools written tomorrow.
- Forensic and legal audio — WAV's uncompressed bitstream is preferred for evidentiary work because every sample is preserved exactly as decoded.
- Hardware that won't decode AAC — Some sampler keyboards, broadcast loggers, and embedded systems read WAV but not AAC; converting up front avoids playback failures.
HEVC Audio (AAC-LC) vs WAV (PCM) — Format Comparison
| Property | AAC-LC inside HEVC | WAV (PCM output) |
|---|---|---|
| Compression | Lossy (perceptual) | None (uncompressed) |
| Typical iPhone settings | 48 kHz, stereo, ~128–256 kbps | Matches source by default |
| Bitrate (16-bit/44.1 kHz stereo) | 128–256 kbps | 1,411 kbps |
| File size, 1 minute stereo | ~1–2 MB | ~10.6 MB at 44.1 kHz, ~11.5 MB at 48 kHz |
| Quality after editing re-saves | Degrades each save | No further loss |
| Patents / royalties | MPEG-4 AAC patent pool | Public domain (Microsoft RIFF spec) |
| DAW native support | Most modern DAWs | Universal — every DAW since the 1990s |
| Embedded / legacy hardware | Frequently unsupported | Near-universal |
Sample Rate Quick Guide
| Sample Rate | Best For | Notes |
|---|---|---|
| 8000 Hz | Telephony, IVR test audio | Narrow-band speech only; music sounds muffled |
| 16000 Hz | Speech-to-text (Whisper, ASR) | Mono recommended; halves file size vs 44.1 kHz |
| 24000 Hz | Voice-over / podcast intermediates | Compromise between ASR and music quality |
| 44100 Hz | CD audio, music distribution | Use if delivering to streaming or pressing CDs |
| 48000 Hz | Video-paired audio (default for iPhone HEVC) | Match the source — avoids resampling |
| 96000 Hz (not offered here) | Studio masters | Up-sampling from 48 kHz adds zero new information |
Frequently Asked Questions
Does converting HEVC to WAV improve the audio quality?
No. The audio inside an HEVC file was already encoded with a lossy codec (typically AAC-LC at 128–256 kbps, sometimes AC-3). Converting to WAV decodes those samples and stores them uncompressed, but the perceptual data discarded during the original encode is gone for good. WAV's value here is preserving what's left without further loss during editing — not restoring detail.
What sample rate and bit depth should I pick for an iPhone HEVC video?
Leave Audio Sample Rate set to "Original" — iPhone HEVC video is captured at 48000 Hz, and matching that rate avoids a resample step. The output WAV is 16-bit PCM by default, which carries far more dynamic range than the source AAC, so the conversion will not bottleneck quality.
Does this extract AC-3 (Dolby Digital) audio from Blu-ray HEVC rips?
Yes. The decoder reads whatever audio stream is inside the HEVC container — AAC-LC, AAC-HE, AC-3, E-AC-3, or sometimes PCM. The output is always WAV PCM. If your source has multiple audio tracks (e.g., 5.1 surround + stereo commentary), the primary track is decoded; multi-track demuxing is not exposed in this tool.
Will the WAV file be larger than the HEVC source?
The WAV contains only audio, so it's much smaller than the full HEVC file (which carries video + audio). However, the audio portion alone is 5–10× larger as WAV than as AAC. A one-hour HEVC source at 48 kHz stereo produces roughly 690 MB of WAV.
Can I extract just the audio from a specific scene?
Yes. Use the Trim controls to set a start time and duration in seconds or HH:MM:SS.sss format. For example, start 00:01:30.500 with duration 45 extracts 45 seconds of audio beginning 90.5 seconds into the video. Only that segment is decoded and written.
Why pick WAV instead of FLAC if both are lossless?
WAV is universally supported but uncompressed (~10.6 MB/min at 44.1 kHz stereo). FLAC compresses losslessly to roughly 50–60% of WAV size while staying bit-identical, but a small number of older DAWs, samplers, and embedded devices don't read FLAC. Pick WAV for maximum compatibility, HEVC to FLAC for archival storage with smaller files.
Is downloading the audio as MP3 better for sharing?
For email or chat sharing, yes — HEVC to MP3 yields a ~1 MB/min file at 128 kbps versus ~11 MB/min for WAV. Use WAV when you'll edit further (each MP3 re-save degrades quality) and MP3 only when the file is the final deliverable for casual playback.
My HEVC file came from a screen recording — will the system audio extract correctly?
Yes. iOS and macOS screen recordings store the captured audio as AAC inside the HEVC container, exactly like camera footage. The converter decodes that track and writes it to WAV. If you recorded with both microphone and system audio mixed, the mix is preserved as a single stereo track — the streams cannot be separated post-hoc.
Can I batch-convert a folder of HEVC clips to WAV?
Yes. Add multiple files in step 1; each is uploaded over an encrypted connection, processed on xconvert's servers, and packaged for download. Total time scales with upload size and connection speed. For trimming the audio further afterward, see the Audio Cutter.
