WAV is an uncompressed audio format — which means no data is lost during recording. This gives our AI the highest-quality input possible, resulting in the most accurate transcriptions. If you have the choice, WAV files will always produce better transcripts than compressed formats like MP3 or AAC.
WAV files are commonly used in professional recording environments: broadcast studios, legal proceedings, medical dictation, academic research, and music production. Our WAV to text converter handles the large file sizes that come with uncompressed audio — files up to 5GB are supported. Speaker diarization separates multiple voices, and timestamps link every word to the exact moment in the recording.

After transcription, export as TXT, Word, PDF, or SRT subtitles. Our AI can also generate summaries and extract key topics from your WAV transcripts. For professional workflows that require archival-quality transcription, WAV to text with Vatis Tech delivers the precision you need.
