Audio Spectrum 2.7

Audio Spectrum is a real-time FFT spectrum analyzer that provides a visual representation of acoustic signals. It offers functionalities for measuring the frequency response of audio equipment and analyzing various sounds, such as those produced by musical instruments.

• Spectrum analyzer
• SPL Meter (dBFS)
• Fast real-time response
• Sampling rates: 44.1kHz, 48kHz, 96kHz*
• Fast Fourier Transform (FFT)
• Window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536
• Zoom and pan
• Measure values
• Possibility to input audio through the built-in microphone or an external microphone (via USB camera adapter or iPhone/iPad dock connector – Core Audio compliant devices)
• Sharing charts via mail, social networks, or clipboard
• Exporting image charts (png) to the iOS 11 Document Browser with iCloud support
• Frequency scale options: linear and logarithmic
• Amplitude scale options: linear and logarithmic SPL/RMS (dBFS)
• SPL meter weighting: dBZ - linear

*For analyzing at a sampling rate of 96kHz, an external microphone with support for this frequency should be used via a USB camera adapter or iPhone/iPad dock connector.
