Podcasting & Audio Tools
Free, practical calculators for every stage of a recording — size your export, estimate an episode's run time, work out bitrate, hit a loudness target, dial in mic distance, and tame a room's reverb. Educational tools for planning your audio, not professional engineering advice.
Audio File Size Calculator
Estimate the megabytes an episode will take from its bitrate or WAV settings and run time — for MP3 and uncompressed WAV — so you know upload and hosting sizes before you export
Podcast Episode Length Estimator
Turn a script's word count and your speaking pace into a run time, or add up your segments, to hit a target episode length before you ever press record
Audio Bitrate Calculator
Work out the uncompressed bitrate from sample rate, bit depth, and channels — in kbps and megabytes per minute — to size raw recordings and pick an export setting
LUFS Loudness Target Calculator
Compare your measured loudness to a platform target like -14 or -16 LUFS and get the exact gain change, with a true-peak clipping check before you publish
Mic Distance & Gain Calculator
Use the inverse-square law to see how moving toward or away from the microphone changes your level in decibels, and the make-up gain needed to keep it even
RT60 Reverb Time Estimator
Estimate a room's reverb time from its dimensions and surface absorption with the Sabine formula, and see whether the space needs acoustic treatment for clean voice
