SpectrumView — Real-time Sound Visualizer for Apple Mobile Devices

SpectrumView, created by Oxford Wave Research Ltd., is an educational reference app that displays real-time spectrograms and frequency spectra on iPhone, iPad, and iPod Touch. It helps users see audible frequencies in their environment and also reveals signals above or below human hearing.

Core capabilities

  • Record audio and play it back directly within the app, with options to export recordings via email or iTunes file-sharing.
  • Hold and freeze peak values in Spectrum Analyzer mode to examine the frequency envelope over time.
  • Manually set minimum and maximum scale values and choose between linear or logarithmic frequency scaling.
  • Clear the spectrogram display on demand to refresh the visualization.
  • Integrate with SoundCloud for uploading or downloading audio files.
  • Open and manage saved recordings and snapshot files through the Files app.

Practical applications

  • Acoustic measurements and troubleshooting for hobbyists and students.
  • Tuning and calibration of musical instruments and audio equipment.
  • Speech analysis and feedback for voice training or research.
  • General exploration of environmental sounds and hidden frequencies.

File handling and sharing

SpectrumView supports local file access via the Files app and provides multiple sharing routes: email attachments, iTunes file-sharing, and SoundCloud connectivity. Recorded sessions can be saved as snapshots or audio files for later review or distribution.
