I've seen it done before, but don't know how it was done.

 Upload the memo on nostr.build then paste the link here

 @nostr.build is that right? 

 Best way I know how.
Nice tunes! 

 Thank you :) 

 Now there is even a better way! 🫡

 Dooope 

 @jb55, i think you mentioned voice notes in a prior post. @Kavinya would be interested in voice notes. 

 I record the audio on my cellphone and convert it to MP4 and sent it as a video hahaha I don't know if it is a stupid way, but it was the way I found to do this. 

 Thanks, I think the nostr.build is a faster solution 🌼 :) 

 @jb55 
a +1 for your idea
