Everything about audio transcription
Which audio format gives the best transcription accuracy?
Uncompressed formats like WAV and AIFF typically give the best results. However, high-quality MP3 files (192kbps+) also produce excellent transcriptions.
Can I convert podcasts to text?
Yes! Upload your podcast audio file in any format and Sonix will transcribe it. You can then create show notes, blog posts, or searchable transcripts.
How do I transcribe voice memos?
Simply upload your voice memo file (M4A from iPhone, or any format) to Sonix. We'll transcribe it in minutes with speaker identification.
Can I transcribe music with lyrics?
Sonix is optimized for speech transcription. While it can transcribe sung lyrics, it works best with spoken content like podcasts, interviews, and meetings.
What's the maximum audio file size?
Sonix supports audio files up to 4GB in size. For longer recordings, our intelligent processing handles them efficiently.

What a great transcript experience! I love the work they are doing at Sonix. Their webpage is really simple to use and yet you get everything you need... most of the time there is very little to no editing on the final text.
I was amazed at how accurate Sonix is.
Sonix is the best transcription program I have worked with.
Holy Cow. It works. This just saved me freaking DAYS of my life. I am totally getting a Sonix tattoo now!
I was surprised in the accuracy from the audio to script. Out of 3 transcripts, only one had to be adjusted. Perfect!!
Your UI and UX was one of the best I've seen. And I've seen a lot of them. Clean, simple, and pretty easy to edit.
I was truly amazed by the quality of the transcript I received from you.
I’m convinced that Sonix at the moment is the best transcription service existing anywhere in the world.
