  • Love this podcast - audio needs work

    The content on this podcast is excellent! However, I find the audio levels for vocals incredibly low and hard to hear for every episode. The intro music is mastered 30-40% louder than the vocals themselves, so the author definitely has a starting point to equalize the audio volume to for the content. Keep it up!
