Tags： Wave Surfer 音乐

WaveSurfer is a powerful audio visualization software that allows users to record and analyze audio files. It enables you to observe the waveform of audio files, examine the characteristics of data signal resonant peaks, and view the spectrogram of video and speech data signals. Here's how to use it:

Recording Audio:

Before recording, right-click on the empty panel and select "Properties" to set the sampling rate, sample precision, and number of channels for your video and speech data signals.

Click the red "Record Video" button on the main interface to start recording. Once done, click the gray "Stop" button to save the audio file.

Observing Audio Waveforms:

2.1 To observe the waveform of an audio file, right-click on it and choose "Create Pane" > "WaveForm". This will allow you to view the frequency domain waveform of the analog signal.

You can also select a specific portion of the frequency domain waveform with the left mouse button to play the corresponding video segment.

By selecting the waveform panel, you can zoom in on the waveform to observe the short-time periodic characteristics of the video and speech data signals.

Right-click on the waveform panel and choose "Waveform Blow Up" to observe the short-time frequency domain waveform, which is the short-time Fourier transform of the video and speech data signals.

Right-click on a specific point on the waveform and select "Spectrum Section" to analyze the resonant peak characteristics of the data signal.

2.2 To view the spectrogram of an audio file, right-click on it and choose "Create Pane" > "Spectrogram". This will allow you to observe the spectrogram of the video and speech data signals.

You can customize the spectrogram color by right-clicking on the spectrogram and selecting "Properties" > "Spectrogram".

2.3 If you find that there are too many panels displaying information, you can right-click on the desired panel and choose "Delete Pane" to remove it.

Software Features:

WaveSurfer offers a user-friendly interface with intuitive controls for recording and analyzing audio files.

It supports various audio file formats, making it compatible with a wide range of devices and applications.

The software provides advanced visualization tools, such as waveforms, spectrograms, and frequency domain analysis, to help you understand the characteristics of audio signals.

WaveSurfer allows you to easily zoom in and out of waveforms and spectrograms for detailed analysis.

The software supports multiple languages and is regularly updated to improve performance and add new features.

How to Use:

Start by recording your audio file using the built-in recording feature.

Once recorded, you can observe the waveform and spectrogram of the audio file using the provided tools.

Analyze the frequency domain characteristics of the audio signal by selecting specific portions of the waveform or spectrogram.

Take advantage of the customization options to adjust the color and display settings of the spectrogram.

If needed, you can delete unnecessary panels to declutter the interface.
