WAV is the format professional recording gear speaks natively. Podcast studios tracking each host on a separate channel, DSLR and mirrorless cameras capturing on-camera audio, handheld field recorders, and older dictation hardware all default to uncompressed WAV because it preserves every detail of the original signal with no lossy encoding in the way. That fidelity is great for editing and mixing, but it also means WAV files are rarely small, and not every transcription tool is built to handle them at their actual size.
Transkio accepts WAV files directly, alongside MP3, M4A, AAC, OGG, OPUS, and FLAC, so you don't need to bounce a studio recording down to a compressed format just to get a transcript. Upload the file, and Transkio transcribes it with 50+ languages, detects who's speaking on multi-mic recordings, and gives you back a transcript you can edit line by line.
Uncompressed Audio Means Uncompressed File Sizes
A single hour of stereo WAV audio can run several times larger than the same recording as MP3, and a multi-track podcast session recorded on separate channels per host gets big fast. That's fine for local editing, but it becomes a real problem the moment you need to transcribe: file-size caps on free or generic tools reject the upload, or the tool silently downsamples the audio before running it through recognition, which can cost you accuracy on exactly the high-fidelity recording you were trying to preserve.
The other issue is workflow. Studio and field recordings often include cross-talk, room tone, mic bumps, and long unscripted stretches — the kind of audio that turns manual transcription into hours of rewinding and retyping, or that trips up transcription tools tuned only for clean single-speaker voice memos.
Upload the WAV File As-Is and Get a Working Transcript Back
Transkio reads WAV files natively — no re-encoding step, no quiet quality loss. Free accounts can upload files up to 100 MB with no card required, which covers most single-episode podcast segments and short field recordings; Ultra raises that ceiling to roughly 8 GB, built for multi-hour, multi-track studio sessions.
On plans with Elite and above, Transkio separates speakers automatically, so a two-host podcast recording or a multi-mic interview comes back with each voice labeled instead of one unbroken block of text. Once the transcript is ready, click any line to jump the player to that moment, fix a misheard word, or rename a speaker — the transcript stays fully editable.

Host 1: So, yeah — welcome back to the show. Um, today we've got a really good one. Host 2: Sorry, go ahead. Host 1: No, you go ahead. Host 2: Okay, so today we're talking about remote work and how it's changed since the pandemic.
Frequently asked questions
Why are WAV files so much bigger than MP3, and will that cause problems?
WAV stores audio uncompressed, so a file can be several times larger than the same recording saved as MP3 — that's normal, not a sign anything's wrong. It only becomes an issue if it pushes you past your plan's upload limit. Free accounts can upload files up to 100 MB, and paid plans raise that ceiling considerably, up to roughly 8 GB on Ultra, so most studio and field recordings fit comfortably.
Does uncompressed WAV audio transcribe more accurately than MP3?
Transkio transcribes WAV files at their original quality with no downsampling, so you keep whatever fidelity your recording gear captured. For most speech, a well-recorded MP3 and a WAV of the same session will transcribe about the same — the real accuracy gains from WAV show up on recordings with quieter passages, subtle audio detail, or background noise, where uncompressed source audio gives the model more to work with.
Can Transkio separate multiple speakers recorded on a WAV file?
Yes. On Elite plans and above, Transkio detects and labels individual speakers automatically, which works well for multi-host podcast sessions and interviews recorded on separate mic channels and mixed down to a single WAV file.
What if my WAV recording has cross-talk or a messy intro?
Transcribe it as-is. The transcript is fully editable afterward — click any line to jump straight to that point in the audio, clean up overlapping dialogue, and rename speakers, rather than trying to get a perfect take before you upload.
Can I get a translated transcript from a WAV recording?
Yes, on Pro plans and above. Transkio produces a translated text transcript of your recording alongside the original — this covers the transcript text; translated SRT/VTT subtitle export isn't available yet.
