Audio Spectrum Analyzer vs Com-Phone Story Maker
Side-by-side comparison of two open source alternatives
Audio Spectrum Analyzer
Audio Spectrum Analyzer was designed with accuracy and ease of use in mind. It can be used for monitoring or measuring environmental sound or noise; help tuning instruments; timing short sound events; and educational purpose. Features: * No Ads. * With log or linear frequency axis. * Can label frequency axis using music pitch note. * Support all possible sampling rates and almost all recorder sources of your device. * Graph with nice grid lines and labels, easy to operate. * FFT sample size range from 64 to 32768. Using half-overlapped (adjustable) time window to increase time resolution. * Various window functions provided, for different frequency resolution and dynamical range. * Peak frequency detection (in unit of Hz and note+cent), with a moderate accuracy (FFT + interpolation). * With dB or A-weighting dB (dBA). * Can record the audio in wav (PCM) format. * Pinch to zoom, drag or swipe to move, long-press to place cursor, double touch to reset zoom. Notes: May need some knowledge of discrete Fourier transform and spectrum analysis to use it well. The actual accuracy mainly depends on your device. No calibration interface provided.
Com-Phone Story Maker
Com-Phone Story Maker helps you create multimedia narratives, combining photos, audio and text in exciting ways to tell digital stories. The app's simple interface helps you create your own photo slideshows to document your life; send to other devices running the application or play back locally; create templates; export as a movie; upload to YouTube; or, save a web version to self-publish. Each story can include any number of media frames. Each individual frame of the story can include an image or photo, up to three layered audio or music tracks, and text content. Anything in a frame can be edited at any time – for example, you can pause audio recording and then resume later, or load pictures from your media library. All elements of each frame are optional. For example, Com-Phone can also be used as an annotated photo diary, a simple audio recorder, a text and sound tool for discussion about current events, or even a multimedia survey app. A simple printable user manual is available at: https://digitaleconomytoolkit.org/manuals/com-phone.pdf. Com-Phone is completely free, with no adverts and no unnecessary permissions. The app is open source as part of the Com-Me toolkit – you can fork any of the Com-Me tools on GitHub: https://github.com/communitymedia.
