Who uses this tool

PODCASTING
Masters any host accepts
WAV or FLAC masters become MP3s that podcast hosts and upload forms with size limits accept without complaint.
VOICE NOTES
iPhone memos that open anywhere
m4a voice memos convert to MP3 so they play in editors, players, and systems that still refuse m4a.
MUSIC & AUDIO
Archive without losing quality
Convert WAV session bounces to FLAC to shrink a library on disk while staying bit-for-bit lossless.
EDUCATION
Lecture audio students can play
Recordings saved in odd formats become MP3s that drop straight into a course page or an LMS.
LEGAL & COMPLIANCE
Recordings in one file format
Standardize a mixed pile of interview and call recordings to a single format for the case or matter file.
CUSTOMER SUPPORT
