A Go library providing digital signal processing packages including FFT, spectral analysis, window functions, and WAV file utilities.
go-dsp is a Go library that provides digital signal processing capabilities, including fast Fourier transforms, spectral analysis, window functions, and WAV file utilities. It solves the need for native DSP tools in the Go programming language, enabling developers to perform signal analysis and audio processing directly within their Go applications.
Go developers working with signal processing, audio analysis, scientific computing, or embedded systems that require DSP algorithms.
Developers choose go-dsp for its idiomatic Go implementation, comprehensive DSP functionality, and ease of integration into Go projects without relying on external C libraries or complex bindings.
Digital Signal Processing for Go
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides idiomatic Go packages, eliminating the need for CGO bindings or external dependencies, as emphasized in the project's philosophy of simplicity and performance for Go developers.
Includes essential DSP operations like FFT, spectral analysis with Pwelch method, window functions, and WAV file support, covering common use cases for signal processing as listed in the key features.
Organized into separate packages (fft, spectral, wav, etc.), allowing developers to import only what they need, reducing bloat and improving code maintainability, as shown in the installation example.
Offers straightforward installation via 'go get' and simple API usage, with a clean example in the README demonstrating FFT computation on real-valued data, making it accessible for Go projects.
Focuses on fundamental algorithms; lacks support for more complex DSP techniques like filter design, modulation, or real-time streaming, which might require additional libraries or custom implementations.
The README is minimal, with only basic installation and a simple example, relying on godoc for API details, which may hinder quick onboarding or troubleshooting for complex tasks without external resources.
While optimized for Go, it may not match the raw speed of native C libraries for intensive computations, potentially impacting applications with large datasets or strict timing requirements, as Go's garbage collection can add latency.
