What is Dynamic Range?
Dynamic range is the difference in volume between the quietest and loudest parts of an audio recording. In podcasting, a controlled dynamic range is preferred for easier listening.
Why Dynamic Range Matters for Podcasters
Dynamic range describes the contrast between the softest whisper and the loudest shout in your audio. While a wide dynamic range is great for classical music or movies, it is often a problem for podcasts. Podcasts are frequently consumed in noisy environments—cars, subways, or gyms. If the dynamic range is too wide, the listener will have to turn up the volume to hear the whispers (risking ear damage when the laughter starts) or turn it down during loud parts (missing the quiet details). Podcasters use compressors and limiters to reduce the dynamic range, creating a 'narrower' but more consistent listening experience where every word is intelligible without adjusting the volume knob.

Background Noise / Noise Floor
Background noise (also called noise floor) is the unwanted ambient sound present in your recording, such as air conditioning hum, computer fan noise, or room echo. It can distract listeners and make your podcast sound unprofessional.
