How to transcribe aac
- 1
Upload your AAC file
Drop your AAC file onto CentClip's upload area - no account, login, or audio conversion required. CentClip accepts raw AAC files directly alongside other common formats, so you can go straight from an Android voice recorder export, a stripped audio track, or a voice message download to processing. Your first 5 minutes are free and need no credit card, which is enough to verify accuracy on a sample clip before committing to a longer file.

Select your language and let the AI transcribe
Choose the spoken language from 50+ supported options so the recognition engine applies the right vocabulary and phoneme model to your audio. CentClip processes the file and returns a time-stamped transcript displayed in a built-in editor where you can correct names, acronyms, or any words the recognizer missed. Most short recordings finish in under a minute - longer files take a few minutes, with live progress visible on screen.

Download your transcript, SRT, or VTT
Export a plain text transcript to paste into a document, research note, or CMS, or download an SRT or VTT subtitle file to attach to a video in your editor or upload to a hosting platform. If you need captions burned directly into a video file, burned-in MP4 export is available from the same results screen. All three output formats are included in the same per-minute rate with no add-on fees.
Why choose CentClip?
AAC is the default audio format for Android and cross-platform recording tools - and most transcription services fumble it
Android voice recorders, Google Recorder, Samsung Voice Recorder, and dozens of third-party apps all default to saving audio as raw AAC or AAC inside a container that comes out as a .aac file when exported. Many online transcription tools only reliably handle MP3 or M4A and either reject AAC outright or silently degrade quality during an automatic conversion step. CentClip processes AAC natively - drop the file straight from your Downloads folder and transcription starts without any intermediate re-encoding or format error.
Voice messages and broadcast exports accumulate fast - per-minute pricing matches how that work actually lands
WhatsApp, Telegram, and Signal all let you export voice messages as audio files, and many come out in AAC. A journalist finishing a source-heavy investigation might have 40 voice messages to transcribe in a single week, then nothing for the next month. Paying a flat monthly subscription for a tool you use in bursts is wasteful. CentClip charges 5 cents per minute with no recurring fee - 20 two-minute voice messages costs $2.00 total, a quiet month costs nothing, and any credits you buy carry forward indefinitely so a batch purchase covers work spread across months.
Clean output formats that slot directly into video editors, podcast platforms, and research archives
AAC files often originate as the audio layer of a video - stripped from an MP4 for faster upload or lighter storage - and the downstream need is usually captions or a searchable transcript, not just raw text. CentClip exports SRT and VTT files that import directly into Premiere Pro, DaVinci Resolve, Final Cut Pro, and YouTube Studio without reformatting. The plain-text transcript includes timestamps for quick navigation. If you need the captions back on a video file, burned-in MP4 export is a single click from the results screen.
FAQ
How accurate is transcription for AAC audio files?
Accuracy is high for clean, single-speaker recordings - typically 95% or better on clearly spoken audio. Files with significant background noise, heavy crosstalk, or very low bitrate encoding may need a few manual corrections in the built-in editor before export.
Is there a free trial, and how much does it cost to transcribe an AAC file?
Your first 5 minutes are free with no account or credit card required. After that, transcription costs 5 cents per minute with no subscription - a 20-minute recording costs $1.00.
Where do AAC files come from, and what export formats does CentClip support?
AAC files commonly come from Android voice recorders, exported voice messages from apps like WhatsApp or Telegram, audio stripped from MP4 video, and broadcast or streaming pipelines. CentClip exports plain text, SRT, VTT, and burned-in MP4.
Do CentClip credits expire if I only transcribe AAC files occasionally?
Credits never expire. Buy a block when you have a batch of files to process and come back whenever your next project arrives - your balance will still be there with no subscription to cancel and no monthly reset.
