Description of OTOTETSU

When electric trains accelerate and decelerate, we can hear some characteristic sounds, which is caused by inverters' controlling the torque and the rotational speed of the motors. This app simulates the waveforms generated by inverters and sounds coming from motors, and you can also design sounds of imaginary trains.

  • Brilliant Recreation

    I Use this app in my spare time or whenever I’m bored, and I love it, creating sounds of existing or imaginary trains is something I love doing, although I would love to see more older styles such as camshaft or dc resistance drive.
  • A couple of suggestions

    I really like this app but can you somehow bring the slider back? I know you can touch the display meter for the same effect, but it's way more sensitive than the slider was as far as I can tell. I don't mind if it's disabled by default.
    Another thing I'm surprised hasn't been implemented but a way to delete presets from your personal library ought to have been added a while ago in my opinion, but the updates have me hopeful.

    This app is a blessing. You are a blessing. Thank you everything!

  • Some Suggestions…

    I am not very sure if this is a glitch. The “Random Width” value is 5 by default. However, it remains 5 even if we switch to synchronous (also the Wide-3 mode) modulation. We have to switch to asynchronous mode and change the value to 0, then switch back to synchronous modulation if we want to hear the “pure” sound.

    Also, could you please consider allowing us to type speed values instead of using the scrolling feature? For iPhone users, the upper-half of the screen will easily come down while scrolling down the speed value.

    Overall, this is a great app!
