Waveshaping Synthesis is a type of distortion synthesis that can create dynamic spectra in a controlled way. In waveshaping, it is possible to change the spectrum with the amplitude of the sound. A simple example of this method is the clipping caused by overdriving an audio amplifier. These simple method creates an astonishing variety of sounds which are very unique and can't be reproduced by any other contemporary synth! microTERA gives you also a method of getting randomly generated sound patches in a way you never experienced before: roll the dice!

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.
