Audio Editor, MP3 Cutter

Review by eFreeware

Most audio editors on Android ask you to trust a slider and hope for the best. What stands out about Audio Editor, MP3 Cutter is that it puts the waveform in front of you and lets you zoom in on it, then nudge the trim points in tenth-of-a-second steps until the cut lands where you want. That combination of a visible waveform and fine-grained adjustment is the core of the app, and it is what I would judge it on.

It is a free download from Hitchhike Tech, sitting in the Music & Audio category and rated for Everyone. The install numbers are substantial: more than 10 million installs and a 4.1 average across 82,253 ratings, which suggests a lot of people have found a use for it. The app carries ads and offers in-app purchases, so it is worth knowing that going in.

Who is it for? Anyone who needs to shorten, split or join audio on a phone rather than a desktop: someone trimming a song into a ringtone, a podcaster cutting a bad take, a student assembling a short audio clip for a project. It is built for editing work.

The app first appeared on August 15, 2024, and the most recent update landed on September 17, 2026, so this is a project that has been kept current rather than left to sit.

Three ways to make a cut

The trimming tool works in three modes, and the choice of mode is really the choice of what you are trying to achieve. Keep selected does the obvious thing: it removes everything on either side of the part you highlighted and leaves that segment alone. This is the mode for pulling one chorus out of a longer track or isolating a single sentence from an interview.

Delete selected works the other way around. You mark the piece you do not want, the app removes it, and the two remaining ends are joined back together. That is the mode for taking out a cough, a false start or a stretch of dead air without leaving a gap behind. Jump cut goes further: you can mark several unwanted segments and have them all removed in one pass, with the surviving pieces stitched into a single continuous file. If you have ever wanted to compress a rambling recording into something tighter, this is the tool for it.

All three modes sit on top of the same waveform view, which you can zoom into for accuracy. The start and end points of a selection can be typed in directly if you know the exact times you want, and there are forward and rewind controls that move in 0.1-second increments for when you would rather nudge than type. I like that both approaches exist, because setting a cut by eye and setting it by number are different habits and people tend to prefer one or the other.

Joining files and shaping the seams

The merger takes several audio files and combines them into one. That is a straightforward enough idea, but the details are what make it useful: you can apply a fade-in at the start of a piece, a fade-out at the end, and an overlap where two files meet. Overlap matters because a hard splice between two tracks often sounds abrupt, and letting one run into the next smooths that transition.

The developer suggests this for compiling fragmented pieces or putting together a medley, and that fits what the feature does. If you record in short sessions and want them as one file, or you are assembling a sequence of clips into a single track, the merger handles that without sending you to a computer. Fades also help when you are trimming a song down and want the result to end cleanly rather than stopping mid-note.

Between the trimming modes and the merger, most of the ordinary editing jobs are covered: shorten, remove, combine, smooth the joins. That is a narrower scope than a full digital audio workstation, and it is a scope that makes sense on a phone.

Formats, limits and what is coming

Format support is broad. The app edits AAC, OGG, FLAC, MP3, MP2, WAV, OPUS and M4A files, which between them cover the audio you are likely to have on a phone or receive from someone else. Not every editor handles FLAC or OPUS, so this is a point in its favor for anyone working with files from different sources.

The developer says trimming is free and that there is no cap on how many edits you can make. That is a meaningful commitment for an app supported by ads and in-app purchases.

Two features are upcoming rather than present. An audio mixer would let you combine multiple tracks and process them together, which is a step beyond the current merger. A ringtone maker would let you set an edited clip as an incoming call ringtone, an alarm or a notification sound, and assign different ringtones to different contacts. Neither is available yet, so anyone whose main reason for downloading is ringtone assignment should know it is on the roadmap rather than in the app today.

What to expect when you open it

The pieces you will be working with are arranged around the act of making a cut rather than around browsing a library or playing music.

You bring an audio file, you work on it, you save the result.

One practical note: the developer invites feedback by email at [email protected]. For an app that is still adding features, that address is the channel for suggesting what should come next.

Where this editor fits

This is a tool for people who edit audio occasionally and want it done properly, not a studio replacement. If your editing needs run to multi-track mixing, effects chains or detailed mastering, the planned mixer is aimed at part of that gap. What it does offer is precise cutting and joining, which is what most phone-based editing actually consists of.

It should suit anyone making ringtones from songs they already own, trimming voice recordings before sharing them, or assembling short audio pieces from several files. It should also suit people who have been frustrated by editors that only let you drag a rough selection and hope. The zoomable waveform and the 0.1-second controls are the answer to that frustration.

The free price makes it easy to try. Ads and in-app purchases are part of the package, so if those bother you, that is a consideration. The 4.1 rating across a large number of ratings suggests most users get on with it well enough.

A capable cutter for everyday audio jobs

Audio Editor, MP3 Cutter does a focused job well: it cuts, splices and merges audio with more precision than most free phone editors bother to offer. The three trimming modes cover the situations that actually come up, the merger with fades and overlap handles the joins, and the format list is wide enough that you are unlikely to hit a file it cannot open.

The caveats are honest ones. It is a trimming and merging tool rather than a full editing suite, the ringtone maker and mixer are still to come, and the app carries ads and in-app purchases. The developer's promise of unlimited free trimming is the strongest argument for trying it.

If that describes the job in front of you, this is a reasonable place to start.
