iAnalyzer vs SPLmap

iAnalyzer is a FFT based professional software to analyze the audio signals for iPhone, iPod Touch and iPad. After 10 years of good sales all over the world, we are glad to see that iAnalyzer has gradually become the industry standard in audio analyze field, due to it's very high quality of course. This is definitely a Must Have app for every musician or sound engineer. We also released the Mac version, you can download it from "Mac App Store". Features: -High performance software design for Real Time Analyzing(RTA) and complex graph displaying. -Works on 44K sample rate, 20~20k Hz frequency output. -FFT spectrum, Octave and 1/3 Octave result display. -Colored curve depend on the dB value. -Flex FFT size, 4K, 8K, or 16K. -Reference Pressure configurable. -2D or 3D or Mix 2D&3D display. -History result display while in 3D mode. -High precision peak frequency computation, average-error lower than 0.1%. -Auto peak frequency tracing, up to 3 peaks can be displayed simultaneously and each one be linked from text to the graph clearly. -Frequency to music scale converter, you can use iAnalyzer as a professional instrument tuner, or to test if any sound is tuneful. -Powerful synthesizer to allow you replay the audio with different speed, from 1/8 to 4x. With this feature, you can listen to your recoding very slowly. (Require iPhone 4S and later, iPad 2 and later which shipped with multiple cores processor.) -VGA output support. Sync display on your device and extern screen. (iPhone 4, iPod touch 4 and iPad required) -Current waveform display and summary waveform display. -Record at any position and red color to mark the latest recording, unlimited recording time. -Play back the recording. -Oscope Auto-Scale: Enable you to view more details for low level signal. -Snap to Peak: Find peak more easily while using measure line. -File Manager: Recording in wave format, create new files, delete exist files, etc. -Wifi Transfer and Data exporting: Download wav files with your browser, including screen shot, FFT result in txt file. -Touch in the result area to use the measure line, bordered label means where is a peak. -Move in the waveform area or touch on the bottom of the area to change the current position, iAnalyzer re-compute and update graph automatically. You can also change the position while playing. Note: -The internal mic of iPhone first generation can only works on 8K sample rate, you need head-set to achieve 44k. -Press "File" button to see the HTTP address, it is in the bottom of the window. -For more information, Please visit http://phyar.cn . How to Use: -Touch and move in the result area with one finger to use the measure line. -Touch and move in the result area with 3 fingers to rotate the 3D graph. -Touch and move in the summary waveform area to move the current position. -Tap in the scroll bar area(bottom of screen) to re-seek the current position.

SPLmap: The Professional Standard for Spatial Acoustic Analysis 1. Introduction: A New Dimension in Sound SPLmap is not just a decibel meter; it is a geospatial acoustic engine designed for the modern sound professional. In an era where live events are under increasing scrutiny from local councils and where architectural acoustics define the success of a space, the ability to visualize sound in its physical context is no longer a luxury—it is a requirement. SPLmap provides a high-performance environment that allows users to plot, track, and manage Sound Pressure Level (SPL) data points across any geographic landscape. From the narrow confines of a jazz club to the sprawling fields of a three-day music festival, SPLmap turns the invisible physics of sound into a clear, actionable visual map. 2. The User Experience: Interface as an Instrument We believe that professional software should get out of your way. SPLmap is built with a "minimalist power" philosophy, utilizing macOS-native design patterns to ensure the learning curve is non-existent for industry veterans. 3. Visual Intelligence: The Color of Sound Data is only as good as its presentation. SPLmap uses a sophisticated color-coding logic that allows for "split-second" situational awareness. The Traffic-Light Legend The app utilizes a standardized, three-tier color scale to categorize acoustic intensity: 4. Technical Architecture: Built for macOS SPLmap is engineered from the ground up using Apple’s most advanced frameworks. This isn't a web-app wrapper; it is a native tool built for performance. Key Monitoring: A dedicated local event monitor listens for the Delete and Backspace keys, allowing for lightning-fast data pruning. MapReader Integration: Using the latest MapReader technology, SPLmap converts screen touches into precise geographic coordinates with sub-meter accuracy. Observation Framework: The app utilizes the latest Swift Observation patterns, ensuring that if one data point changes, the Legend, the Map, and the Detail View all update simultaneously with zero latency. Geographic Precision Leveraging MapKit, SPLmap supports: Standard, Satellite, and Hybrid Views. 3D Realistic Elevation: Essential for understanding how sound travels over hills or is blocked by urban structures. Local Fallback Logic: The app intelligently defaults to the user's real-world location but includes a London-centric fallback for pre-planning sessions when location services are restricted. 5. Professional Use-Cases Live Sound & Festival Management For FOH (Front of House) engineers, SPLmap is the ultimate tool for monitoring noise leakage. By placing measurement points at the venue's "Noise Sensitive Locations" (NSLs), engineers can ensure they are delivering maximum impact to the crowd while remaining strictly within the legal limits defined by local authorities. Architectural & Industrial Safety Safety officers can use SPLmap to create a permanent record of noise exposure on factory floors or construction sites. By mapping "Red Zones," companies can better design hearing protection protocols and environmental baffles to protect their workforce. Urban Planning & Hospitality Restaurant and venue owners can map the "acoustic footprint" of their spaces. This helps in identifying where tables might be too loud for conversation or where the sound system needs more distribution to eliminate "dead spots." 6. Conclusion: Your Venue, Decoded. SPLmap bridges the gap between the microphone and the map. It is an essential addition to the toolkit of any professional who works with sound in the physical world. By offering a blend of high-level geographic visualization and granular data management, SPLmap ensures that you are always in control of the environment.
