To convert a cassette, play it in a working cassette deck and record its analog output on a computer. Save an uncompressed WAV master first; then export MP3 listening copies or use CD-authoring software to make an audio CD. For ordinary tapes, a USB cassette player is the simplest setup. A conventional deck connected to a USB audio interface offers more control when sound quality matters.
Choose a transfer method
| Your situation | Practical setup | Trade-off |
|---|---|---|
| One or two ordinary tapes; simplest setup | USB cassette player or deck and recording software | Fewer components, but quality varies by device and transport. |
| You already have a cassette deck | Deck connected to a computer line input, or preferably a USB audio interface | More control over playback and capture; requires the right cable and input. |
| Many valuable tapes | A reliable, well-maintained stereo deck and USB audio interface | More setup, but a better-controlled signal path. The condition of the tape and deck still matters most. |
| Damaged, moldy, or irreplaceable tape | Stop and consult a professional digitization service | Costs more, but avoids risking further damage through repeated playback. |
A USB cassette device must support audio capture over USB; USB power or a USB connection used only for playback is not enough. Check the device’s specifications. A computer may label a working USB capture device “Microphone” or “USB Audio CODEC.” Audacity’s USB recording guidance explains device selection and external interfaces.
What you need
- A cassette tape and a player or deck with working playback.
- A computer and audio-recording software such as Audacity.
- A USB cable for a USB cassette device, or an audio cable connecting your deck’s output to a computer input or USB audio interface.
- Storage space for the recordings, plus an external drive or other backup destination.
- For a conventional audio CD: blank CD-R discs and a computer with a writable optical drive, or access to a separate CD burner.
Common connections include RCA left/right outputs to an audio interface’s line inputs, RCA to a stereo 3.5 mm input, or a 3.5 mm headphone output to a computer line input. A 6.35 mm headphone socket may need a 6.35-to-3.5 mm adapter. For USB, use the cable or adapter that matches your capture device and computer. Match an output to an input; do not connect two outputs together. Audacity’s equipment connection guide illustrates common setups.
Prepare the tape and deck
- Inspect the cassette shell. Do not play it if the shell is cracked or warped, tape is spilling out, or you can see mold or tangled, folded tape.
- If the tape and mechanism appear sound, check that the tape is wound fully onto one reel. Fast-forwarding and rewinding once can help distribute tension, but skip this if the cassette is already squealing, dragging, or behaving abnormally.
- Test playback briefly. Stop if the tape squeals, slows, stops, sheds visible debris, or begins to tangle. Do not keep pressing Play or try repeated playback on an irreplaceable tape.
- Clean the deck’s heads and tape path according to the deck manufacturer’s instructions. Check that playback speed is steady and that the transport is in good condition.
- If you know the cassette was recorded with Dolby noise reduction, use the matching playback setting. If unsure, compare a short sample with the likely setting and with Dolby off; the wrong setting can make the sound too bright, noisy, dull, or muffled.
- Turn off unnecessary sound enhancements, noise suppression, and automatic gain control on the computer or capture device.
A conventional cassette deck’s line output is generally preferable to a computer microphone input. Mic inputs are meant for a different signal level and may be mono or apply unwanted processing. Use a true line input where available; if the computer has none, a USB audio interface with line inputs is a useful alternative. The deck supplies the playback; the interface converts its analog signal to digital. It cannot correct a poor tape or faulty deck.

Record the cassette in Audacity
Install Audacity from its official site. Its device controls and menu names can change between versions, so look for the recording-device and channel settings if the labels differ from these instructions.
- Connect the USB cassette device or audio interface before opening Audacity. If you connect it afterward and it does not appear, restart Audacity or rescan its audio devices.
- Insert the cassette and rewind to the beginning of Side A. Open a new project.
- Select the cassette device, audio interface, or computer line input as the recording source. For a USB device, select the actual device as the input—not “Stereo Mix” just because an old guide suggests it.
- Set recording channels to 2 (stereo) and choose your headphones or speakers as the playback device.
- Play the loudest expected passage and watch Audacity’s recording meters. Adjust the capture input so peaks reach about −6 dB, leaving room to avoid clipping. Adjust the recording input, not your speaker volume.
- Stop and rewind. Press Record in Audacity, then Play on the deck. Capture the whole side, including a little silence before and after the material. A 60-minute cassette side takes roughly 60 minutes to record at normal speed.
- Stop playback and recording at the end of the side. Save the project and export an unedited, lossless capture before editing. Repeat for Side B, either in the same project or in a separate one.
If the waveform hits 0 dB and its peaks look flat, the signal may be clipped; turning it down afterward cannot restore the lost detail. A somewhat quiet but clean capture can usually be amplified or normalized later. Audacity’s recording FAQ covers input selection, stereo capture, and level setting.
Keep a master, then make listening tracks
Keep an untouched full-side recording as your reference. WAV is uncompressed and widely supported; FLAC is a lossless alternative that uses less space. Audacity’s tape digitization workflow describes saving a raw WAV capture, editing from a working copy, and backing up the results. For most home transfers, a clean lossless master is more useful than making the only copy an MP3.

Make edits on a copy of the capture:
- Trim excess silence before the first track and after the last.
- Split the long recording at song boundaries or meaningful spoken-word sections. Zoom in, place each boundary carefully, and listen through it to ensure you have not cut off speech or music. A pause does not necessarily mean a new chapter or track.
- Add labels or track markers, and use short fades at cuts where needed to avoid clicks.
- Remove obvious handling noise only when you can identify it confidently. Keep an unedited or minimally treated master in case an edit causes a problem.
Noise reduction, filtering, equalization, and click removal can help in some cases, but use them lightly. Cassette hiss cannot be removed perfectly; strong noise reduction may sound watery or metallic. Software cannot reliably restore missing treble, undo clipping, or repair severe wow and flutter. Audacity’s instructions explain splitting recordings into separate tracks and exporting them.
Export MP3 files
After keeping your WAV or FLAC master, export separate MP3 files for a phone, computer, or portable player. MP3 is lossy, so it is convenient for listening and smaller storage, not a substitute for the lossless master. Choose a high-quality constant- or variable-bitrate setting for music; speech can often be encoded at a lower bitrate. Avoid repeatedly converting an MP3 into another MP3, which adds more lossy compression.
Add useful metadata before or after export: tape title, artist or speaker if known, side, track number, and year if known. A clear folder structure—such as the tape title followed by “Side A” and numbered tracks—will make the files easier to identify later. Audacity lists supported formats, including MP3, WAV, and FLAC, in its official FAQ.

Make a CD for a conventional CD player
Use CD-burning software that explicitly offers Audio CD or Music CD authoring. Simply copying MP3 files onto a disc creates a data CD, which may not play in an older standalone CD player.
- Export the edited tracks as 44.1 kHz, 16-bit PCM stereo WAV files for CD authoring.
- Open your burning software and choose Audio CD or Music CD, not data disc. Add tracks in the intended order and check the gaps between them.
- Burn and finalize the disc, then test it in the player you plan to use.
If a CD will not play, check that you made an audio CD rather than a data disc, finalized it, and used a disc type supported by the player. A finished CD is one useful copy, not a permanent or infallible backup. Audacity’s cassette-to-CD tutorial covers the broader transfer workflow.
Back up the files
Keep at least two independent copies, for example on your computer and an external drive; cloud storage can provide another copy. Retain the raw full-side capture, edited lossless tracks, and MP3 listening files. Consider saving a short text note with the tape title, capture date, deck and connection used, Dolby setting if known, software, and any processing. This context makes it easier to understand or redo a transfer in the future.

Troubleshooting
No sound is recorded
Confirm the cassette is playing and that the cable runs from a deck output to a computer or interface input. Verify Audacity’s selected source and that it is set to stereo; check that the device is not muted in the operating system and that the cable is fully inserted. If the USB device was connected after Audacity opened, restart or rescan. Make sure the device supports USB audio capture, not only USB power or playback. Audacity’s USB recording guidance covers input selection.
The recording is distorted
Lower the recording input level and aim for peaks around −6 dB. Check whether you used a microphone input instead of line input, or whether a capture device’s gain is too high. Disable automatic gain control and other processing. If distortion persists, check the deck and tape path; a dirty head or a faulty, overloaded converter can also be responsible.
Recommended Free Tools
The recording is very quiet or has only one channel
Check the selected input, any separate capture-device gain controls, and the deck’s output or headphone volume. Inspect the cable and left/right RCA connections. If the tape was recorded in mono, it will not contain missing stereo information; retaining it in a stereo file does not make it stereo. If only one channel appears from a stereo recording, check for a loose, damaged, or incorrectly wired cable and confirm that the input is not being treated as mono.

The speed or pitch is wrong
A worn belt or capstan, incorrect deck speed, or a tape recorded on a misaligned machine can change pitch or cause uneven playback. Try a different well-maintained deck if available. Minor speed errors may sometimes be corrected in software, but severe mechanical instability is not reliably repairable there.
The tape stops, squeals, or tangles
Stop playback immediately and eject carefully; do not touch the tape surface or keep retrying. If it is tangled, visibly damaged, moldy, or irreplaceable, consult a specialist rather than attempting repeated home repairs. “Baking” is not a routine DIY treatment for ordinary compact cassettes.
When to use a professional service
Consider a professional digitization service if a tape is rare, moldy, damaged, mechanically unstable, or especially important—or if you have a large collection and lack a reliable deck. Check that the provider accepts standard audio cassettes, what file formats it returns, how it handles damaged media, and how it protects and returns originals. Availability and prices vary by service and location; confirm the current terms directly rather than assuming a video-transfer offer includes audio cassettes.
