AAC (Advanced Audio Coding) is a compact, high-quality audio format commonly stored as .aac. It's a lossy format like MP3 but typically offers better perceived audio quality at the same bitrate, which makes it popular for mobile recordings and many recording devices.
Choose AAC when you need a small file with good audio fidelity, e.g. for mobile interviews, voice memos, or streaming exports. Compared to WAV it saves space, compared to MP3 it usually provides cleaner voice quality at equal bitrate. AAC balances storage and clarity, especially for on-device recordings.
Transcribing AAC files instantly makes your audio content searchable, accessible, and easy to repurpose. Create articles from interviews, generate captions for videos, pull quotes for reports, or find key moments in your research without scrubbing through audio. For teams, a searchable transcript library dramatically speeds up workflow and fact-checking.
Upload your .aac file to SpeechText.AI service, choose language/model, then run transcription. Edit the result and export to PDF, DOCX, TXT or captions.

Yes, once the transcription of AAC files is complete, you can instantly export the text as a professionally formatted PDF document. You can also choose from several other formats, including Microsoft Word (DOCX), plain text (TXT), and subtitle files (SRT, VTT).
Higher bitrate and clearer voice recordings yield the best results. Avoid heavy background noise. A quiet, close mic recording at 44.1-48 kHz works best.
