You may have seen the Facebook ad: “Generate with AudioLab — free voice generator, frontier AI voice models at no cost.” It sounds almost too good to be true, so we took a closer look at the app behind the ad. Here is our complete, honest review of AudioLab: what it is, what it does, how to use the voice generator, and — most importantly — how long it actually stays free.
What AudioLab Is
AudioLab is an Android audio editing app made by HitroLab, a developer based in India. Its full name on the Google Play Store is “AudioLab Audio Editor Recorder & Ringtone Maker,” and its package name is com.hitrolab.audioeditor.
The numbers are impressive: the app has passed 40 million installs according to AppBrain, and holds a 4.66 to 4.7-star rating from roughly 320,000 to 335,000 reviews. The latest version is 1.3.33, updated on October 3, 2026, and it requires Android 8.0 or higher. The app is actively maintained — it was updated within the last two weeks at the time of writing.
Under the hood, AudioLab is built on FFmpeg (under the LGPL license) and the Superpowered SDK, which explains how a mobile app can offer this much audio power.
Key Features
AudioLab is not just a voice generator — it is a full audio toolkit. Its main features include:
- Audio trim, cut, split and merge — including a dedicated MP3 cutter for songs and voice clips
- 4-track music mixer with DJ effects and filters for making remixes
- Voice recorder and voice changer
- Text-to-speech (AI voice generator) — type text and have it read aloud in an AI voice; this is the feature the Facebook ad is promoting
- Vocal remover and isolator — strip vocals from a track for karaoke, or isolate them
- AI noise and silence reduction for cleaning up recordings
- Ringtone maker — cut any audio and save it as a ringtone, alarm or notification tone
- Video-to-audio converter, audio format converter and tag editor
- Volume booster, 3D/spatial audio effects and batch editing (convert or mix multiple files at once)
The home screen presents all of these as a clear dashboard of tools, and edits offer instant preview so you can hear every change as you make it.
The Free Voice Generator
This is the feature from the ad. AudioLab’s text-to-speech tool lets you type or paste any text, pick a voice, and generate spoken audio from it — useful for video voiceovers, podcast intros, narrating posts, or just having articles read aloud to you.
We could not find any published time limit, expiry date, or character cap on the free voice feature from official sources. The ad’s claim of a “free voice generator at no cost” appears to refer to the app’s free, ad-supported tier. Our honest reading: the voice generator works free of charge in the free version, but if you need it heavily or for professional work, you will likely run into the limits of the free tier and need the paid upgrade.
How to Download and Use
Download: The safest way is the Google Play Store — search for “AudioLab” and look for the developer name “HitroLab – Mp3 Audio Editor and Ringtone Maker Dev” (package com.hitrolab.audioeditor). The app is also distributed as an XAPK on third-party sites like Uptodown and APKFab, but the Play Store version is the one we recommend.
Using the voice generator, step by step:
- Install and open AudioLab.
- From the tools dashboard, choose Text to Speech.
- Type or paste the text you want spoken.
- Pick a voice from the available options.
- Tap generate, preview the result, then save or share the audio file.
Pricing: How Long Is It Free?
The app is free to download and free to use — and that includes the voice generator. There is no trial period after which the app stops working.
The catch, as with most free apps, is advertising: the free version contains ads. There are also in-app purchases and PRO features that unlock the app’s full power. We could not verify the exact PRO price from official public sources, so we will not quote one here — but one Play Store reviewer noted that a Google Play Pass subscription ($4.99/month) removes ads and in-app purchases across supported apps, AudioLab included.
Bottom line: “free” means the ad-supported free tier, with no verified expiry. Expect to pay if you want an ad-free experience or the advanced PRO tools.
Things to Know Before Installing
- Ads: the free version shows ads — this is how the “free” model is funded.
- Data collection: according to its Play Store listing, the app may share location, app activity and device IDs with third parties, and may collect location, app activity and two other data types. Data is encrypted in transit and you can request deletion.
- A real user-reported limitation: one voice-actor reviewer noted that the AI denoising tool requires audio clips longer than 10 seconds — a problem if you work with very short clips.
- Similar names, different products: do not confuse AudioLab with Audialab (audialab.com — AI music production plugins) or AI Voice Lab (various web-based text-to-speech tools). Same-sounding names, completely different products.
Verdict
AudioLab is a genuinely capable, well-reviewed, all-in-one audio editor that happens to include a free AI voice generator — the feature in the ad is real, not a gimmick. With 40 million installs and a 4.7-star rating, it is one of the most trusted audio tools on Android. If you can live with ads, you may never need to pay. If ads bother you or you need the PRO tools, that is the trade-off to weigh. For casual voice generation, ringtones and quick audio edits, it is hard to beat at the price of free.
