Stage Plot Maker helps you build clear, readable stage plots to communicate your band's technical requirements to a sound engineer. You can build a collection of stage plots for different kinds of gigs, then print or email them directly from your mobile device. Running the app on a tablet is recommended for building stage plots. Once you build a stage plot, you can copy it to the phone app for quick access on the go. Stage plots can include a diagram to show the placement of elements on stage; numbered input and output lists; a list of other required items like chairs and music stands; the name and photo of each performer; notes for the sound engineer; and your contact info. Note that this app doesn't use pictures for small instruments like guitars, trumpets, etc. Instead, it uses symbols for the inputs that those instruments go into, like mics or DI boxes. You can label those inputs to show what instrument they are used for. This provides a streamlined display that shows sound engineers just what they need to set up the stage for you. The app does include symbols for large instruments like piano and drums that are typically placed on stage first with the inputs positioned around them. Please see the screen shots and demo video for examples. *** If you have a problem or a suggestion, please contact me before writing a bad review.

Professionals and enthusiasts alike can now access Smaart’s Real Time Analyzer, beautifully rendered Spectrograph, and crystal clear SPL meter without needing to set up a dedicated personal computer to run a desktop version of Smaart*. Smaart RTA is capable of the same accuracy, precision, and ease of use enjoyed by live sound engineers and FOH professionals across the world using the same underlying algorithms as its desktop siblings*, trusted by sound engineers to deliver accurate and actionable data in real time. *PLEASE READ Smaart RTA creates single channel measurements only. It does not support the dual channel transfer function measurements or impulse response measurements used for system alignment and optimization, including time alignment. -- SMAART RTA INCLUDES -- -PROFESSIONAL STANDARD RTA (REAL TIME ANALYZER) GRAPH- The RTA display helps engineers ensure an audio mix or playback balance aligns with the desired tonal response for a specific artist, performance, or specification – providing real-time analysis of frequency content and confidence that you are hearing what you are seeing. Features include: Fast, Slow, None averaging options for graph response ballistics. 1/48, 1/24, 1/12, 1/6, 1/3, 1oct Banding for precision frequency resolution. 1/3 octave x-axis frequency scale for intuitively identifying center frequencies and trends. -BEATIFULLY RENDERED SPECTROGRAPH- The Spectrograph is essential for managing and controlling feedback and identifying problem frequencies, allowing engineers to quickly visualize and address potential issues before they interfere with a performance. Features include: Adjustable dynamic thresholds to customize the amplitude levels represented by the spectrograph. 1000 slices in history, allowing you to ‘rewind’ the display to view events that already happened. Intuitive color palette to represent amplitude level (dark to bright, quiet to loud). -CLEAR SPL DISPLAY WITH DB LEVEL METER- The SPL view helps you ensure audio levels remain consistent from one show to the next or check levels for uniformity across various locations within a venue. Features include: Standard SPL metrics of A & C weighting, with fast and slow response times. NIOSH and OSHA exposure percentages correspond with nationally accepted U.S. recommendations and occupational health and safety guidelines. Large Level Meter display for distant viewing. The default settings for all functions in Smaart RTA mirror those in the desktop version of Smaart v9’s real time single channel measurements. -- ADDITIONAL SMAART RTA PRO FEATURES -- Smaart RTA Pro includes the functionality of Smaart RTA and unlocks all settings and advanced features, including: Adjustable RTA Graph Settings (frequency scaling, bars/lines, line thickness, grid interval, etc) Plot Calibrated Levels to view the RTA graph relative to SPL, rather than Full Scale level only. Target Curves (Cinema X Curves included, or import your own). Capture and store RTA data traces, allowing you to compare multiple responses across different locations or venues. Average multiple stored RTA data traces to view a spatially averaged frequency response. Adjustable RTA graph Y-offsets to apply a visual dB offset to live or captured data. Import/Export RTA files (.srf) to and from Smaart desktop. Additional SPL Traffic Light display for staying within venue SPL Limits. Internal and external microphone calibration for SPL. Due to Apple's distribution policies, free trials require a subscription selection. If you would like to try Smaart RTA before you buy, start with a subscription, then cancel it to avoid billing.
