Read full description

Zeitmaschine is an audio engineering calculator with 4 different modes to compute tempo and distance related delay times, convert time related values and to calculate file sizes. DELAY TIME MODE Zeitmaschine is a delay time calculator with all divisors and multipliers relative to the time measurement you have done. Calculate delay times in milliseconds (ms) and beats per minute (bpm). Set the desired tempo via the tab-button, or write it down in ms/bpm, all options will be computed and a huge amount of 21 matched delay times will shown up at once, including dotted and triplet values. Take these determined times and put it to the delay time display of your effect or sound device, use it to set the right attack and release times of your dynamics (compressor/gate) or set the perfect pre delay time of your reverbs in addiction to the song tempo. Works with virtual-, 19“-, or stage devices (display needed). Zeitmaschine is a pretty quick app, brilliant for live engineering, where you can choose the perfect delay time in seconds, without scrolling the knobs of your FX-device back and forth. On the other hand you got an ultimate overview of alternative delay times, that´s great for doing experiments while mixing a track in a recording studio or in your DAW. You can use it on drums, vocals, guitars, ….you name it, and give them a complete new rhythmical structure. CONVERTER MODE Convert beats per minute to milliseconds, samples & hertz, depending on the audio sample rate. FILESIZE MODE Set the duration, bit depth, sample rate and channel number and get the filesize information for uncompressed files. Add the kbps rate to get the filesize for compressed files. DELAY LINE MODE Set the distance to main P.A. in meter or feet, add the temperature in Celsius or Fahrenheit and get the right delay times to delay the main P.A. to the backline and the line P.A. to the main P.A.

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.
