SpecStream Audio Spectrum Plot

View audio spectrum in real time

Features & Capabilities

App gets audio data from microphone and plots the real time spectrum in the form of a scrolling image.

App settings:
• Sample Rate = the sample rate (in Hz) at which the microphone will be read. Most devices support up to 48 kHz. High-end devices support up to 192 kHz.
• FFT Buffer Size = the size (in samples) of the audio buffer used to compute the FFT. Must be a power of 2, min = 128, max = 16384. Bigger value gives better frequency resolution. Smaller value gives better time resolution.
• Min. Dispalyed Frequency
• Max. Displayed Frequency
• Gain (dB)
• Displayed Time Window (in milliseconds)
• Frequency Grid Step (in Hz) = will draw horizontal division lines
• Time Grid Step (in milliseconds) = will draw vertical division lines moving together with the plot.

Free version limitations:
• sample rate = 8000 Hz (fixed)
• FFT buffer size = 512 (fixed)

Users can upgrade to Premium Version via in-app purchase (one time payment).

Premium version advantages:
• configurable sample rate.
• configurable FFT buffer size: 128, 256, 512, 1024, 2048, 4096, 8192, 16384.

Planned features for future app updates:
• show spectrum of audio file
• export spectrum to file

User Reviews

Users find SpecStream Audio Spectrum Plot simple and functional for basic spectrum plotting but frequently mention its limited frequency range, lack of customization options like axis scaling or color changes, and absence of meaningful graph references. Several users desire features such as the ability to enlarge the display, load files, and better interaction beyond just pausing, indicating that while the app serves as a basic tool, it needs enhancement to be more useful and informative.
Pros
  • Simple and effective at what it does
  • Fulfills its basic purpose as an audio spectrum plot
  • Detailed and works well according to some users
  • Easy to use with basic controls like pause
Cons
  • Limited frequency range capped around 2000-4000 Hz
  • No options to customize frequency axes or display units
  • Cannot enlarge or change colors of the graph
  • No reference grid or graph background, making interpretation difficult
  • Lacks ability to load files instead of real-time input

Simple but effective. Exactly what it should be. Only wish it would go above 4000Hz but that may be my devices limitation I'm not sure.
