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.
