Studio Calculator vs EQ Ear

Studio Calculator is your go-to app for fast, smart, and accurate music-related calculations. Simply add the values you know and the app will intelligently figure out what it can calculate for you.. No more digging through menus or websites mid-session. Stay in focus and get instant answers for: BPM & tempo calculations Delay & phase alignment Time-stretch & pitch shift Duration & file size Frequency to MIDI note Frame-based timing for video ...and much more ### Real-World Examples: • Microphone delay in samples? Just enter the distance in meters. The app gives you time in seconds, samples, and more (automatically adjusted to your sample rate) • Need all delay times for a BPM? Tap or enter the BPM—see delay times in ms, seconds, or Hz instantly. • Have a 2-bar loop and want the BPM? Enter the loop length in seconds or samples and the number of bars and get the correct BPM for any time signature. • Changing from 440 Hz to 432 Hz? Input both frequencies and get the pitch shift in semitones and the time-stretch percentage. • Song duration from BPM and bars? Enter BPM and bar count, total time is calculated. • Working in 6/8? Input your metronome tempo to get the DAW’s BPM. • Total time of multiple songs? Add all times and get the sum. • Need to know disk space for a 75-minute multitrack? Enter the time, set your sample rate, bit depth, and channel count; your file size is calculated. ### Features: • Clean, minimalist UI with dark mode • Copy any result and reuse it as new input. • Tap tempo input for fast and accurate BPM entry • Supports irregular, simple, and compound time signatures • Accurate 64-bit floating-point calculations • Share an image of your calculation • Built-in support for 9 standard frame rates • Frequency -> MIDI note conversion • File size calculations based on duration and audio specs • Customizable: sample rate, bit depth, channel count, time signature, tuning and frame rate • Collapsible results for a clean overview ### The Studio Calculator is your perfect assistant. Give it the values you have, and it will calculate everything there is to know. More calculations are coming! If you’re missing a calculation, let us know, your feedback is much appreciated.

Most producers learn to see a mix before they can hear one. EQ Ear works the other way round. Every question is audio first. You hear a loop, you make a call, and you find out exactly how close you were — in hertz and decibels. FIVE WAYS TO LISTEN EQ — Move four faders until your curve locks onto the track. Bass, low-mid, high-mid, treble. Compare — Two mixes, one band moved. The sliders are locked, so you diagnose by ear alone: which band, and was it boosted or cut? Pinpoint — Forget four broad bands. Name the exact frequency, from 125 Hz to 8 kHz, on a logarithmic scale that shows you where each one really sits. Tempo — Drum loops from 60 to 200 BPM. Tap along, read your pulse, lock your internal clock before you open the DAW. Recall — Hear a take. Five seconds of silence. Hear it again. Did the tone change, or is your memory filling in the gaps? A PATH, NOT A QUIZ 900+ questions across nine categories of music. Every lesson mixes three of the five modes, so you never settle into one kind of listening. Start with First Training — four bands, no genre, nothing to memorise. Then move into vocals, guitar, piano, pop, electronic, rock, classical, jazz and hip-hop. Each one carries its own frequency problems: sibilance in a vocal, mud in a guitar, sub weight in an 808. SEE EXACTLY WHAT YOU MISSED Getting it wrong is the lesson. After every round you see your curve drawn against the track, band by band, with the hertz and decibels you were off by. Then you can play the loop again with the correct EQ applied and hear the difference you could not hear a minute ago. Retrying a lesson is always free. Take a level as many times as you need. SURVIVAL MODE When you want to stop studying and start competing: all five modes, every category, endless. Speed feeds your score, one miss ends the run, and your best resets every week. BUILT FOR EARS THAT WORK Four bands mapped to real ranges — 20-250 Hz, 250-500 Hz, 500 Hz-4 kHz, 4-20 kHz — colour-coded everywhere in the app so the map stays in your head. Clean filters, seamless A/B switching with no click, and loops that keep running while you decide. Practice mode lets you pull any single mode out of the lessons you have finished and drill it on its own. Weak on tempo? Run tempo only. Streaks, XP and ranks track the long game, from Tin Ear upward. WHO IT IS FOR Producers and mixing engineers who want faster decisions. Musicians who want to hear what an engineer hears. Anyone who has stared at an EQ curve wondering whether they are fixing the sound or just moving it. No theory. No notation. No prior training. PASSES AND PLUS Passes open new lessons. You start with ten and get more every day, so you can work through the app for free at a steady pace. EQ Ear Plus removes the limit: every category, every lesson, unlimited Survival runs, no waiting. The full tutorial is free and always will be. Headphones or monitors strongly recommended. Phone speakers cannot reproduce the low end, and the low end is half the training.
