Can you play back a voice memo while it is still recording?

No — not the part that already happened. A recording that is still open is being written to, not read from, and an iPhone cannot do both to the same file at the same time. Here is what that actually comes from, and what is available while you wait.

It is a specific kind of itch: someone says a name or a number worth double-checking, a thought lands exactly the way you wanted to phrase it, and the recording is still running when you first feel the urge to go back and hear it again. Reaching for a scrub bar that is not there is a natural instinct — every other audio app on the phone has one — and it is worth knowing why the recording screen does not.

Why a file being written cannot also be scrubbed

Recording and playback are opposite directions through the same pipe. While a recording is running, audio is flowing one way — from the microphone, through an encoder, onto disk — continuously and in real time. Playing back an earlier part of that same file means reading it, which is a different operation running the other way. A phone can do one or the other to a given file at a given moment, not both, for the same reason a tap cannot fill a glass and empty it at once.

It is not a matter of the app choosing not to build the feature. The file itself is not in a state that supports it yet — see the next section — and even if it were, playing audio back out loud while the microphone is still open runs straight into the feedback problem covered in the guide on monitoring a recording live: whatever comes out of the speaker gets picked up by the same microphone that is still recording.

The file is not actually finished yet

A recording in progress is an open file with an undetermined final length — audio keeps landing on the end of it for as long as you keep going. Audio and video containers, m4a included, are built around having a defined structure once they are complete: a known duration, an index of where things are, a start and an end. Reading a file usefully — jumping to a point five minutes in, showing a scrubber, reporting a length — depends on that structure existing. None of it does yet, on a file that could still grow by another hour depending on what you do next.

That is the same reason a recording only becomes something you can browse, search or export once it has actually stopped. Stopping is not a formality; it is the step that turns a stream of audio still arriving into a finished, readable file.

What the recording screen gives you instead

The one real way to hear it before the recording ends

If checking that earlier moment genuinely cannot wait, the only honest option is to stop the recording, listen to it as a finished file, and start a new recording afterward if there is more to capture. That closes the current file — making it playable, with the earlier moment reachable by scrubbing or by jumping straight to a marker — at the cost of a short gap while nothing is being captured and two files instead of one continuous recording, the same trade-off stopping mid-session always carries.

For most of what this comes up during — a lecture, an interview, a meeting — that trade is not worth it for a single name or number. Dropping a marker on the spot and continuing costs nothing and leaves the exact place to check once the recording is done; stopping outright is worth reserving for something you genuinely cannot afford to keep guessing about until later.

How Voice Studio handles this

The recording screen shows a live waveform and lets you drop a marker with a tap — both work the moment audio starts flowing, and neither requires reading back anything already captured. Playback, including jump-to-marker and playback speed, lives in the Detail view instead, which only exists once a recording has stopped and become a finished file with a real duration. Pro’s live monitoring lets you hear the current microphone input through headphones while recording, which is the closest thing on offer to listening while it happens — it is monitoring the live feed, not replaying anything already on disk. If an earlier moment genuinely needs checking before the recording ends, stopping and reopening the file in Detail view is the same move it would be in any recorder, on any phone.

Common questions

Can I scrub or fast-forward within a voice memo that is still recording?

No. The file is still being written to and has no fixed length yet, so there is nothing for a scrubber to seek within until the recording actually stops.

Can I at least hear what the microphone is picking up while recording?

Yes, through Voice Studio’s Pro live-monitoring feature, over headphones. That is the current input in real time, not a replay of something already said a few minutes earlier.

Do markers let me jump back to a moment while the recording is still running?

No. A marker saves the exact timestamp as you drop it, but jumping straight to that point is something you do afterward, in the Detail view, once the recording has stopped and become a playable file.

What should I actually do if I need to check something said a few minutes ago, right now?

Stop the recording, listen to the finished file, and start a new one if there is more to capture. It costs a short gap and a second file, so it is worth doing only when the moment genuinely cannot wait until the recording is done.
