Frequently Asked Questions
How do I convert AAC audio to text?
Upload your AAC recording or paste a public direct audio link, select the spoken language, and start transcription. Once the file is decoded, Whisper Web turns its speech into editable text. Review the result alongside the recording, then copy or download your transcript.
Can I transcribe AAC files for free?
Yes. Free local transcription supports files up to 20 minutes and 200 MB each, without signup or a credit card. You can edit and export the result on this page. Pro adds cloud processing for longer recordings, batch uploads and saved history.
Why won't my AAC file open?
Local transcription relies on your browser to decode the audio. Some AAC files may not be supported by your browser, even when the file extension is .aac. If the tool cannot read your recording, export a WAV or MP3 copy from an audio app and try again. Renaming the extension alone does not convert the file.
Do I need to convert AAC to MP3 first?
Try the original AAC recording first. If your browser can read it, no extra conversion is needed. If decoding fails, use a WAV or MP3 copy. Changing the format will not restore speech that was unclear or missing in the original recording.
How accurate is AAC transcription?
Results depend on the spoken language, recording quality and selected model—not just the AAC format. Clear speech gives the best results, while background noise and overlapping voices can cause mistakes. Listen back to check names, numbers and important quotes before sharing the text.
Can I edit an AAC transcript before exporting?
Yes. Search the transcript, edit paragraphs and replay passages using their timestamps. Your corrections are included when you copy or download the text. You review the transcript yourself; Whisper Web does not include a human proofreading service.
Can I convert AAC to Word, TXT or subtitles?
Yes. Export the transcribed speech as Word (DOCX) or TXT, with optional timestamps. SRT and VTT subtitles, JSON export and text copying are also available. These downloads contain your transcript, not a new audio file.
Which languages can I transcribe from AAC audio?
Whisper Web supports 98+ languages, including English, Spanish, French, German, Chinese, Japanese and Korean. Choose the language spoken in the recording or use automatic detection. This page transcribes speech in its original language; it does not automatically translate the result.
Can I import an AAC file from a link?
Yes, if the URL points directly to a public audio file that your browser can access. YouTube pages and private Google Drive or Dropbox sharing pages are not direct audio links. If importing fails, download a recording you own or have permission to use and select the local file.
Does my AAC recording stay on my device?
Free transcription processes the audio locally in your browser. Pro uploads your media for cloud transcription and saved history. Copy or download local results before closing the tab, since local edits are kept in the current tab.
