On an old tape, what can be fixed is level: input levels and volume are adjusted for maximum clarity, and the blank tape at the start and end is trimmed. What cannot be fixed is sound the tape never captured. Hiss, dropouts, and an off-mic voice are part of the original recording, and we do not invent what was not there. Uneven levels, a weak channel, and dead air at the head of the reel are fixable. Good editing recovers the best version the tape can give, and because magnetic tape keeps breaking down, that best version is better today than it will be next year.
- Standard editing: input level and volume adjustment, plus trimming blank tape at both ends.
- We do not invent sound that was never captured on the tape.
- Audio is priced by the hour of actual sound recovered – blank tape is never charged.
- Cassettes are $20 per hour of sound; reel-to-reel is $40 per hour of sound, with a $40 minimum when any reel work is on the order.
- Need a long recording split at specific points? Ask when you order.
You already know the tape is not great. You want to know what is salvageable.
Here is the situation most people are in. There is a shoebox with four or five cassettes in it, one labeled in handwriting you recognize, and you have played maybe thirty seconds of one. It was quiet. Somebody coughed. The voice you were listening for was there and also not quite there.
So the real question is not “can you transfer this.” It is “how much of this can be saved, and is anyone going to be honest with me about the rest.” That is what this page is for.
What “audio editing” actually means on a family tape
Most people picture a studio engineer with sliders, scrubbing away every imperfection. That is not what a family tape needs, and often not what it can survive. When we convert audio cassettes and reel-to-reel tapes to digital, the editing is deliberately conservative: set the input level so loud passages do not clip and quiet ones stay audible, adjust overall volume, and cut the silent leader and trailing blank tape.
That restraint is the point. Heavy noise reduction scrapes the top off a voice along with the hiss, and Grandpa ends up sounding like he is talking through a pillow.
Fixable vs baked in
The most useful thing we can hand you is a plain list of which defects respond to work and which do not. Below is that list, with the actual step taken where a step exists.
| Defect | Verdict and what is done |
|---|---|
| Low or uneven levels | Fixable. Input level is set at capture and overall volume adjusted so quiet passages stay audible without clipping the loud ones. |
| One dead or weak channel | Usually improvable. Channel rebalancing brings the surviving channel forward so the recording plays evenly rather than favoring one side. If a channel truly captured nothing, nothing can be added. |
| Speed drift (wow and flutter) | Mostly baked in. Playback is done on properly maintained decks, but pitch wander recorded onto the tape at the time stays on the tape. |
| Sticky-shed squeal, shedding oxide | Sometimes recoverable, handled case by case before playback. This is a binder problem in the tape itself, not something editing addresses. Tell us if a tape squeals so it is never forced through a deck. |
| Azimuth-caused muffling (dull, high end missing) | Often fixable. Playback head azimuth is adjusted so the head sits square to the recorded track, which can bring back highs the tape does hold. |
| Print-through pre-echo (faint ghost before a loud sound) | Baked in. It is a magnetic imprint from adjacent tape layers and is part of the recording. Storing tapes tails-out slows it from getting worse. |
| Tape hiss | Baked in, and we leave it. Hiss occupies the same frequencies as consonants and laughter, so pulling it down hard pulls the voice down with it. |
| Off-mic voices (someone at the far end of the table) | Baked in. If the microphone never picked the voice up, no processing puts it there. Level work can only raise what exists, along with the room noise around it. |
| Long stretches of dead air and blank leader | Fixable and standard. Blank tape at the start and end is trimmed, and blank tape is never charged. |
Some hiss and dropouts are part of the original recording, not a flaw in the transfer. Our answer to “will my old recording sound perfect?” is deliberately unglamorous: we recover the best version the tape can give.
One tape, and what restraint sounded like
March 2026. A customer in Sacramento sent a single Maxell UD 7-inch reel, recorded 1974, a family Thanksgiving with four generations at the table. The reel arrived slightly dished at the edges, the pack loose, tails-out – which was lucky.
Two things were wrong. The right channel played at roughly half the strength of the left, and the whole recording sounded like a blanket had been thrown over it. The blanket was azimuth: the tape had been recorded on a deck whose head was not square. Adjusting azimuth on playback brought the high end back, and channel rebalancing evened out the sides.
What we did not do: touch the hiss. There is a steady tape hiss under that entire dinner, plus a refrigerator hum. A noise reduction pass would have flattened it and taken the youngest grandchild’s voice, thin and high and off-mic, along with it. The customer got back a file where the words are intelligible end to end, the levels are even, and the room still sounds like a room in 1974. She wrote back that she could finally hear her father say grace.
You do not have to place an order to hear what restraint sounds like. Below are two 15-second before/after clips from real customer tapes, shared with the owners’ written permission. One shows an azimuth correction; the other shows hiss deliberately left alone. Fifteen seconds tells you more than any paragraph we could write. If you would rather hear your own tape first, we can still send a short before-and-after sample from your recording before we finish the order.
Clip 1 – azimuth correction, 1974 reel-to-reel (used with permission). Before: dull and blanketed, the high end missing because the recording deck’s head was not square to the tape. After: playback azimuth adjusted so the head sits square, bringing back the highs the tape still holds. Nothing was added that the tape did not contain.
Clip 2 – hiss left alone, family cassette (used with permission). Before: levels uneven, steady tape hiss under the voices. After: input level and volume adjusted, blank tape trimmed, hiss untouched. Hiss sits in the same frequencies as consonants and laughter, so pulling it down hard would have pulled the voices down with it.
Why waiting costs you signal
Magnetic tape is a physical medium with a binder that breaks down, and every year in a hot attic or damp basement costs a little more of what is left. Earlier digitization preserves more quality. Editing works with whatever the tape still holds, so the sooner it reaches a deck, the more there is to work with.
Before you ship: a check you can do tonight
You do not need to place an order to do this, and it will save you grief either way. Twenty minutes with the box is enough.
- Listen for a squeal or chirp on playback, and look at the deck heads afterward for a brown or rust-colored powder. That is shedding oxide, a sign of sticky-shed. Stop playing that tape and flag it to us rather than trying again.
- Wind a reel by hand and watch for a snapped or lifting splice, usually a shiny piece of tape at a join. Note it. Do not tape it back together with office tape.
- Store and ship reels tails-out, meaning fully played to the end rather than rewound. It slows print-through, the faint pre-echo you sometimes hear before a loud word.
- Send the cassette in its case, and send reels in their boxes if you have them. The case protects the edges, and old handwriting on the box is often the only clue to what is on the tape.
- Label each tape with what you think is on it, even if you are guessing.
- Flag any tape you want split, with approximate break points.
- Tell us if a recording is quiet or was made at a distance, so levels get watched closely.
Trimming, splitting, and file delivery
Every tape comes back as one clean, level-adjusted file with the blank tape trimmed off each end. That covers most orders: one side of a cassette, one interview, one recital.
If you want a long recording broken into separate tracks – each song at a recital, each question in an oral history – say so when you place the order and tell us roughly where the breaks fall. Our page on splitting a long recording into separate tracks explains how those requests are handled.
What editing costs, and why blank tape is free
Audio is priced by the hour of actual sound recovered, not by the length of the tape. A 90-minute cassette holding 22 minutes of a wedding toast is billed as 22 minutes of sound.
Cassettes are $20 per hour of sound and reel-to-reel is $40 per hour of sound, with a $40 minimum whenever any reel work is on the order, and blank tape is never charged.
Level adjustment and trimming are included, not an upsell. The full breakdown is on our audio pricing page.
Sound that comes off film is a different job
Sound on Super 8 magnetic-stripe or 16mm film needs a separate projector pass and is then matched to the picture in the editing system, as the full explanation of film sound capture describes.
What we cannot edit for you
We only transfer content you own the rights to, such as family recordings, recitals, sermons and interviews, not commercial copyrighted material like a band’s released album, so ask before you ship if you are unsure (see also the FAQ below on what we convert).
Frequently asked questions
What file format, bit depth and sample rate do you deliver?
Ask when you order and we will confirm the delivery format for your recordings before work starts. Whatever the container, the audio is delivered as one clean, level-adjusted file per tape with the blank tape trimmed off each end, and no processing is applied that strips character out of a voice.
How long does audio transfer take?
Turnaround depends on how many tapes are on the order and how much actual sound each one holds, since audio runs in real time on a deck. Tell us what you have when you order and we will give you an estimate before anything is charged. Tapes flagged as squealing or spliced are handled case by case and can take longer.
Why does my cassette sound muffled, and can that be fixed?
Often it is azimuth: the recording deck’s head was not square to the tape, so the high frequencies read back weakly. Adjusting azimuth on playback can bring much of that back. If the dullness came from a distant microphone instead, it is baked into the recording.
What does a squealing tape mean?
A squeal or chirp, often with brown powder left on the playback heads, points to sticky-shed – the binder holding the oxide has absorbed moisture. Stop playing it and let us know when you order, so the tape is not forced through a deck and stripped further.
Can you split a long recording into separate tracks?
Each tape is delivered as one clean, level-adjusted file by default. If you need it split at particular points, tell us when you order and we will do our best to accommodate the request.
How much does audio transfer and editing cost?
Pricing is by the hour of actual sound recovered. Cassettes are $20 per hour of sound; reel-to-reel is $40 per hour of sound, with a $40 minimum whenever any reel work is on the order. Blank tape is never charged, so a mostly empty tape costs very little.
What happens if a tape fails mid-transfer, and am I charged?
Audio is priced by the hour of actual sound recovered, so you are only billed for sound we actually get off the tape. If a tape breaks down partway through, we tell you exactly what came off it and what did not. Some heavily degraded tapes have limits, and we would rather be honest about what a given tape can give than pretend otherwise.
Can dropouts or a dead channel be patched from a second pass?
Sometimes the playback itself improves on a second try: troublesome tapes are run in multiple decks to get the best possible signal, which can minimize dropouts. But a second pass cannot add sound the tape never held. A weak channel can be rebalanced so the surviving side comes forward; if a channel truly captured nothing, no number of passes will put something there.
Can you transfer a commercial music album from cassette?
No. We only convert content you own the rights to, such as family recordings, recitals, or interviews. Commercial copyrighted material like a band’s album is off limits.
Is the audio from my Super 8 sound film edited the same way?
Not quite. Picture is captured frame by frame without a projector, but sound requires a separate projector pass, and the two are matched up afterward in the editing system. That pass carries some risk, so the machines are kept in brand new condition and closely monitored.
A simple next step
Run the check above on the box tonight. Then tell us what you have, what squealed, and where you want splits, and we will tell you what to expect before anything is charged. No box has to ship this week. But the tape is not waiting for you, and the voice on it is the only copy.
One tape we could not save
Honesty about limits means naming a tape that lost. In late 2025 a customer in Fresno sent three Ampex 641 7-inch reels, recorded in the mid-1960s, a grandfather reading letters aloud. Two of them came back fine. The third had spent decades in a detached garage in the Central Valley, boxed on a concrete floor, through summer after summer of heat and the damp that comes off a slab in winter. That reel arrived warped at the edges with a loose, cupped pack.
Before: on a first careful pass the tape squealed within seconds and left brown oxide powder on the heads, and what came through was a smeared, intermittent murmur with a word surfacing every few seconds. Classic sticky-shed, with the oxide layer physically leaving the backing.
After: nothing better. We tried the reel in more than one deck, which is standard for troublesome tapes, and the best pass gave us roughly four minutes of partial audio out of an estimated thirty, with the voice still unintelligible. There was no editing move left. Level adjustment can only raise what exists, and what existed had come off the tape and onto the heads. We stopped rather than keep grinding what was left of the oxide off, told the customer exactly that, and charged nothing for it: audio is billed by the hour of actual sound recovered, and we had not recovered any.
That is the shape of the promise on this page. We pursue the best possible result and are honest about what a given tape can give, and sometimes what it can give is nothing. Those two surviving reels were stored in the same garage. The difference was luck and a few feet of shelf, which is the whole argument for not waiting.
