spwave 0.9.0-1
spwave is a cross-platform audio editor designed for research and advanced analysis. It supports a wide range of audio formats, including WAV, AIFF, MP3, Ogg Vorbis, FLAC, ALAC, raw PCM, and more via plug-ins. spwave offers precise editing tools such as zoom, crop, fade in/out, gain adjustment, and region extraction. It enables detailed spectral and phase analysis and supports unlimited undo/redo. Users can drag and drop files, edit metadata, save labeled regions, and view multiple synchronized waveforms. Internally, spwave processes audio in 64-bit precision, ensuring high accuracy. It runs on Windows, macOS, and Linux, making it a reliable and flexible tool for audio research and editing.
spwave has following features:
- Support for multiple platforms: Windows, macOS, Linux (Motif, gtk), etc.
- Support for WAV, AIFF, MP3, Ogg Vorbis, FLAC, ALAC, raw, and text files by using plug-ins.
- Support for many bits/samples: 8bits, 16bits, 24bits, 32bits, 32bits float, 64bits double.
- Converting the sampling frequency and the bits/sample of a file.
- Playing, zooming, cropping, deleting, extracting, etc. of a selected region.
- Fade-in, fade-out, gain adjustment, channel swapping, etc of a selected region.
- Editing file information that supports comments of WAV and AIFF, and ID3 tag of MP3.
- Analysis of a selected region using several analysis types, e.g. spectrum, smoothed spectrum, phase, unwrapped phase and group delay.
- Undoing and redoing without limitation of the number of times.
- Waveform extraction by drag & drop.
- Opening files by drag & drop.
- Autosaving of selected regions (you can do this by drag & drop also).
- Saving positions and regions as labels.
- Viewing some waveforms and setting regions synchronously.
- Almost all processing is 64 bits processing internally.
Supported Formats:
- Read/Write: WAV, AIFF, AIFC, CAF, MP3, Ogg Vorbis, FLAC, ALAC (.caf, .mp4), WMA (Windows), APE, AU/SND, PARIS, NIST, IRCAM, raw PCM, text.
- Read-only: MPEG-2 Layer 3 MP3, RMP files with VBR support.
With 64-bit internal processing, autosave capabilities, and synchronized multi-view waveform editing, spwave is a solid tool for anyone handling complex audio editing or acoustic research.

- Fixed a bug that spectrogram view after zoom-in with large factor sometimes freezes.
- Fixed a bug that scroll and zoom-out in spectrogram view after zoom-in with large factor do not work correctly.
- Fixed a bug that spectrogram view provides sometimes wrong time information.
- Fixed a bug that plugin errors sometimes cause a crash.
- Fixed a bug that the color of grid lines is wrong in printing.
- Optimized layout of spectrogram view for printing.
- Enhanced the function of waveform cropping from label information.
- Fixed a bug that some items in the preference dialog related to labels do not work.
- Added some items related to the region label in the preference dialog.
- Fixed a bug that drawing selected region in the log-frequency axis does not work correctly.
- Added partial support for the dark mode of Windows (the menu bar and the menus).
- Fixed a bug that the cursor to indicate current calculation position of spectrogram is sometimes not shown.
- Changed drawing of cursor information into that with white background so as to make the information legible.
- Fixed a bug that moving to the head by scrolling the overview display sometimes fails.
- Added feature of alignment of the view region between spectrum view and spectrogram view.
