Compress Audio for WhatsApp — Reduce File Size Free
WhatsApp has a 16MB file size limit for audio in most countries. A long WAV recording or FLAC file can exceed that easily. Compress to MP3 at 64–96kbps here and your audio will send instantly in any WhatsApp chat.

Compress Audio FreeWhatsApp audio limits and how to work around them
WhatsApp audio messages recorded in-app are already compressed. But when you share an existing audio file (from Voice Memos, a recording app, or a music file), WhatsApp applies its 16MB limit. Compressing to 128kbps MP3 first means even a 30-minute recording stays well under that limit.
