Training in a muay thai gym in chiang mai, thailand. Three minutes of general gym ambience with a personal trainer speaking in thai with a student and training their technique with bag/pad work.
Boxing gym sounds: speedbag, heavy bags, punching mitts, sparring, round timer bells, traffic passing open garage-bay doors. Recorded with a zoom at a traditional boxing gym. Zoom recorder.
I was at the gym. It was in the evening. The gym was full. It was a weights machine, you can hear the weights clinking against each other. It makes a clanging sound.
Recorded with a zoom h4n in 44100 hz stereo. This is recorded in a small high school gym with a small crowd. Lots of sneaker squeaks, whistles, crowd reaction and at the end, a buzzer.
Multiple people working out in a smaller gym. Mostly weight lifting and muscle training on equipment. Lots of metal noises, people talking unintelligibly in the background (in german). Recorded with a ebs stereo array of neumann km184 onto a zoom h4.
This is not the greatest recording ever, but you may find some use for it. Single player dribbling a basketball in an open gym. Some of the dribbling is deliberate and slow, other dribbling a more regular pace. This was recorded in an open gym so there is no ambient sound of crowds or other people other than the hum of the gym lights.
