RTA Audio vs DSP

RTA Audio Realtime analyzer with recording and Visualizer module with export. ••• Realtime analyzer ••• Realtime analyzer gives you the ability to analyze realtime audio input (built-in microphone or external audio accessory inputs) using Fast Fourier Transform with selected window function. You can also record the input for future offline processing or export. ••• Visualizer ••• This module presents you the results of offline audio analysis. Selecting previously captured recording gives the graph view, spectrogram and waveform of the audio data. Simple controls gives you the ability to play, loop, seek and change rate of the recording synchronized with analysis data presentation. Export function allows you to share or archive your analysis. Resulting PDF document contains basic recording information, spectrogram, peak & RMS graph and frequency table data with maximum peaks (with the time of the occurrence in recording) ••• Features ••• Resolution: 1/2 - 1/96 Octave Logarithmic frequency scale Fixed frequency range (20 - 20kHz) Tone scale view C₀- H₈ (A₄ = 440Hz) Peak hold graph Peak average graph RMS average graph Pointer (watch) function Peak and RMS input meter ••• Audio input specification ••• Audio session mode - measurement Input gain control Sample rate: 48000 Hz Bit depth: Float32 Channel: 1(mono) Frequency range: 20Hz - 20kHz Dynamic range: -100dB - 0dB ••• FFT (Fast Fourier Transform) specification ••• Frame size: 8192 Overlap: from 60% to 90% Smoothing Window: Bartlett-Hann, Blackman, Blackman-Harris (default), Blackman-Nuttell, Cosine, Flat Top, Gauss, Hamming, Hann, Lanczos, Nuttall, Rectangular, Triangular Hardware acceleration

The app DSP-CONTROL allows you to adjust the WALL-05DT, MEGA-DSP, DSM-26LAN, DSM-48LAN, DSM-48DT, STA-1000DSP and DSP-26 speaker systems directly via iPad. With this user-friendly app, it is possible to activate presets and make individual adjustments. You can use all the features normally provided by the PC software. Thus, it is possible to adjust 10 equalizers with 8 filter functions, delay, limiter, gain and low cut. With the control software, the following parameters can be adjusted: • Activating and storing presets • 10 equalizers for each channel with the filter functions: bell, notch, all-pass, low-shelf, high-shelf, band-pass, high-pass, low-pass • Delay • Limiter • Gain control for each input • Master volume • Low cut filter This app has been optimised for the iPad.
