P930 Lunar Lander vs Studio Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
P930 Lunar Lander
This app is a sophisticated audio effect instrument designed to create depth and motion in sound. It combines a plate reverb engine inspired by classic studio units with an analog-style BBD delay, offering extensive control over sonic characteristics and routing.
- Plate reverb engine inspired by classic EMT-140
- Digital reverb diffusion reminiscent of Lexicon 224
- Analog-style BBD delay with modulation
- Triple saturation (Plate, Delay, Output)
- Series or parallel routing options
- Advanced ducking for vocal clarity
- AUv3 support

P930 Lunar Lander goes beyond a delay and beyond a plate reverb. It is a space-shaping instrument built to create depth, motion, and musical emotion with a level of control rarely found on iOS. Its reverb engine draws from the character and behavior of classic studio plates such as the EMT-140, and the spacious diffusion style heard in units like the Lexicon 224, while adding modern bandwidth shaping, harmonic excitation, and advanced routing. The BBD delay brings analog-style movement, widening, slapback, and rhythmic echoes with modulation, filtering, and optional noise. Push the plate for bright metallic shimmer or ease the input for warm, vintage smoothness. Blend delay and reverb in series or parallel, enhance the wet path with P42-style saturation, and use mix laws, ducking, and stereo tools to place your sound exactly where it belongs. Highlights • Plate engine inspired by classic EMT-140 behavior • Diffusion and tonal shaping reminiscent of early digital classics like the 224 • Analog-style BBD delay with modulation, regen, and filtering • Triple saturation (Plate, Delay, Output) • Series or parallel routing • Advanced ducking for vocal and mix clarity • Multiple wet/dry blend laws • Ping-pong, stereo offsets, and phase tools • AUv3 support Lunar Lander is not another effect. It is a new way to shape the space around your sound.

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.
