KataPlay

I wanted to listen to music while I was out. However, once you step outside the house, it is full of danger if you can't hear the sounds around you. You always need to be aware of your surroundings in this day and age when a child is riding a bicycle on the sidewalk from behind. At least in Japan. Therefore, I thought that bone conduction earphones would be safe because I could hear the surrounding sounds, so I tried them immediately, but the road in front of my house is a main road with a lot of traffic, noise and vibration, and bone conduction earphones are useless. I thought, "Then why not just use one earbud?" Luckily, these days you can get cheap earbuds that are divided into two pieces that support Bluetooth. So I created a music player that converts stereo music to monaural and plays it only from one earphone. That is KataPlay. The effect was outstanding, and even when I used it on the main road in front of my house, the surrounding sounds and music were perfect. I provide the basic concept part for free. Above is the basic part, so you can use without fee. From here, we will introduce the functions of the paid version (small one-time charge) for more convenient use of this app. The reason why I wanted to listen to music while I was out in the first place was ringing in my ears. I thought I was hearing noise from electronic devices all over the house, but one day I realized that I could hear it even in a park where there were no electronic devices. I was diagnosed with novel corona a while ago, so it may be the aftereffects. In any case, there is no established treatment for tinnitus. But people should live without worrying about ringing in the ears. While creating and using this app, I began to wonder if it wouldn't be nice to keep putting strain on only one ear. That's why I added a mode in which, with earphones attached to both ears, the music is played only from one side, and the earphone that produces the sound alternates every few tens of seconds. This is pretty cool, so now when I go out, I usually play music using this mode. However, when I use it in my house, when it's quiet, I get ringing in the ear from silent side of earphone. I wanted to get rid of this, so I added a mode that lets you play music from one ear and white noise from the other. White noise works great for my tinnitus, and when I'm listening to music in this mode, I completely forget about my tinnitus. At home, where it's safe to use both earphones, I want people like me who suffer from tinnitus to try it. Of course, you can adjust the volume of music and noise separately. Tinnitus is disturbing when you sleep. So I made it possible to hear the noise from both ears when the music is not playing. After 1 hour in this state, the noise stops automatically, so you can sleep with peace of mind. In addition, as an attempt to confuse the brain and reduce tinnitus, we are experimentally adding a mode that plays sounds at random positions and a mode that rotates the position. For advanced users who can cut out one BGM loop of old game music in WAV format using something like Audacity, I made it possible to specify an infinite loop. No matter how long it takes, keep listening until you get tired of it. In addition, in the paid version, you will be able to specify whether it is a continuation of the previous song when arranging by folder name. Songs flagged as a continuation will always be played in a medley even during shuffle playback. The app doesn't have the functions that ordinary music players have, such as searching by name input, fast-forwarding/rewinding, etc., but it was created with an emphasis on safe and secure listening outside . Please try it.
