Audio Spectrum 2.7

Audio Spectrum functions as a real-time FFT spectrum analyzer, providing a visual depiction of acoustic signals. Its applications include measuring the frequency response of audio equipment and analyzing various sounds, such as musical instruments.

Key features include:

• Spectrum analysis capabilities
• SPL Meter (dBFS) for sound pressure level measurement
• Rapid real-time response
• Supported sampling rates: 44.1kHz, 48kHz, 96kHz*
• Fast Fourier Transform (FFT)
• Variable window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536
• Zoom and pan functionalities for detailed analysis
• Measurement readouts of actual values
• Audio input options include the built-in microphone and external microphones via USB camera adapter or iOS dock connector (Core Audio compliant devices)
• Chart sharing via email, social media, or clipboard
• Export of chart images in PNG format 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

*Please note that analysis at 96kHz requires an external microphone capable of supporting this sampling rate when used with a USB camera adapter or through the iPhone/iPad dock connector.
