Convert WAV to MP3.
Compress large WAV recordings into portable MP3s at high bitrate. Then transcribe them with TranscriptAI.
WAV vs MP3: quality vs portability
WAV is uncompressed audio — pristine quality, but enormous, around 10 MB per minute. MP3 is compressed: a small fraction of the size and playable on essentially every device and app. Converting is how you turn a bulky studio or voice recording into something you can email, upload or carry around without eating storage.
Does it sound worse?
MP3 is lossy, but at a high bitrate the difference is inaudible for speech and very hard to pick out for music. Keep the WAV as your master if you'll edit or archive it; reach for MP3 whenever the goal is sharing or playback.
Recording you want transcribed?
A smaller MP3 uploads faster and transcribes just as well — once it's converted you can send it straight to TranscriptAI for a transcript, summary and notes.

WAV to MP3: re-encoded
MP3 is a compressed, lossy audio format, so this re-encodes the sound and the file gets smaller. Every lossy re-encode sheds a little quality, so convert from the best source you have rather than chaining conversions.
