So this is my attempt in making a crowd sound effect. It really didn't sound like a people's crowd since I said "walla" too loud in some clips. There are approximately 28 clips in that sound varying from 15 to 17 seconds. Also, I combined another crowd sound effect which I created in 3ML Editor and edited in both Audacity and Adobe Audition to make it longer.
All (with the exception of the earlier crowd sound effect I did) was combined in Audacity. Sharoud(no) 聲道:2 類型:mp3 creatures、Crowd、speaking、talking、walla 生物、人群、請講、說、沒有 資料來源:freesound ( https://freesound.org )
