kandi X-RAY | JWave Summary

JWave is a Java library typically used in Video, Video Utils applications. JWave has no bugs, it has no vulnerabilities and it has low support. However JWave build file is not available and it has a Non-SPDX License. You can download it from GitHub.

Java implementation of a Discrete Fourier Transform (DFT), a Fast Wavelet Transform (FWT), and a Wavelet Packet Transform (WPT) algorithm. All algorithms are available in 1-D, 2-D, and 3-D. The wavelet transform algorithms are using normalized orthogonal or if available orthonormal wavelets. The comon wavelets like Haar, Coiflet, Daubechies, Symlets, and Legendre are available. Additionally there are also some Bi-Orthogonal and unusal wavelets implemented - in total around 50 wavelets. The implementation of JWave is based on several software design patterns and - hopefully - appears therefore user-friendly.

When you open a file for output, that tells the operating system to immediately truncate the file to zero bytes long.

To make it clear to people who don't know the difference ... this is not the same as deleting the file.

The only way to not truncate the file is to open it in "append" mode. But that means that new data will be written the end of the file, which is probably not the right thing to do with a ".wav" file.

If you don't want the file to be truncated immediately, and append mode is wrong, only open the file when you are ready to start writing data to it.

If you want to replace a complete file with another complete file, then you need to 1) write the new data as a temporary file in the same directory, and then 2) rename the new file in place of the old one.

Install JWave

You can download it from GitHub.
You can use JWave like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the JWave component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
