Equal loudness in the Wavelet app makes all frequencies equally loud so mid frequencies won't overpower low and high frequencies.

TL;DR

  • Wavelet has added a new feature called equal loudness that makes all frequencies equally loud.
  • This is helpful because, when you lower the volume of your music, low and high frequencies start to dip more than mid frequencies.
  • To celebrate the update, the developer has given us 100 promo codes to give away.

Note: The giveaway was 22hrs ago. i noticed the article now. So, the chance of getting any promo code are slim to none.
