MIKELOSS
Record a better-sounding podcast — free calculators for audio file size, episode run time, bitrate, LUFS loudness targets, mic distance, and room reverb, plus plain-English guides to microphones, recording gear, and producing a show.
From sizing your export and estimating an episode's run time to hitting a platform's loudness target, dialing in mic distance, and taming a room's reverb, MikeLoss pairs free hands-on audio calculators with plain-English guides and a richly illustrated museum of recording and broadcast history. Record cleaner, publish with confidence.
Podcasting & Audio Tools
Free calculators for every stage of a recording — audio file size, episode length, bitrate, LUFS loudness target, mic distance and gain, and room reverb.
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
Sound & Broadcast Museum
Wander an immersive museum of the machines and ideas that gave voice a permanent home — the microphones that capture sound and the ribbon and condenser designs behind them, the phonographs, tape, and records that stored it, the studios and mixing consoles where it was shaped, and the radio and broadcast era that carried it to millions, each in its own gallery, so you can get to know the story behind every era of recorded sound: how each tool came to be, what it changed, and the role it still plays in how we listen today.
