Introduction

spwave is an audio file editor supporting several sound formats including WAV, AIFF, MP3, Ogg Vorbis, FLAC, ALAC, raw, and more. The program is designed for research use, so stability and usability are regarded as important. spwave runs on multiple platforms including Windows, macOS, and Linux.


Features

spwave has following features.


Supported Files


Install

On Windows and macOS, you can install spwave just by unpacking the archive. However, if you want to move the executable to another folder, you have to move plug-ins with it. If you don't do that, spwave can load no files. Linux version requires installing plug-ins (spPlugin 0.8.2 or higher) before installing spwave. Using RPM version (for Redhat-based Linux) or deb version (for Debian-based Linux) is easier way.

Uninstallation can be simply done by removing files. You can remove the files safely because spwave doesn't use the registry and doesn't replace system files. If you installed RPM/deb version on Linux, you should uninstall it based on the usage of RPM/deb.

To compile the source code on Linux/Unix, see How to compile.


Supported Platforms

spwave is known to work at least on Windows 7/8/10/11, macOS 10.14-13.2, and Linux (CentOS, Ubuntu, etc.).


Bugs

A level meter introduced from version 0.6.7 does not display exact amplitude.

Although support of ASIO driver is added in version 0.6.11-2b, ``ASIO Multimedia Driver'' doesn't work well. Please use an ASIO driver of an ASIO supported device. Since ``ASIO Multimedia Driver'' is used for non-ASIO devices, you probably don't suffer from that practically.

Window scrolling in Windows Media Audio file which is supported by version 0.6.12-4b does not work correctly (the time position does not coincide with the actual time line). It has not been clarified yet if the problem is caused by the Microsoft's library or my implementation. If you have trouble with the problem, please save the file as the WAV format.

Mac OS X (Carbon) version has a bug that right-click of a mouse doesn't work correctly on the waveform overview display. macOS Cocoa version doesn't have this problem.


Bug Report

If you have questions or find bugs, please send me an e-mail. Please include the following information when you report bugs.

Including `spwave' in the subject of the e-mail is also helpful for me.

I have received many e-mails related to saving as MP3. The function saving as MP3 is turned off as default to avoid the license and patent related problems of MP3. To turn on the function, you have to download and install the MP3 output plugin. Please download and install the plugin if your condition agrees with the condition at the official site.


License

spwave is free software. Please see LICENSE.txt included in the archive for more information.
