Sonic Visualiser 是一款开源音频分析和注释工具，可显示音乐文件的波形，让您深入了解输出声音背后的含义。

支持多种格式并支持导入

它主要面向音乐技术人员，可以图形化地显示每个通道的音频信号，并对加载的数据进行注释，以便更轻松地识别片段。

它旨在提供一个用户友好的工具来显示声谱图和音频波形，确保兼容一些最常见的音频格式（例如 WAV、MP3、AIFF、AVR、FLAC、OGG、RAW）以及一些不太常见的文件类型（AU、CAF、HTK、IFF、MAR、MPC、PVR、RF64、SDS、W64、WVE、XI）。此外，它还允许您从本地存储的 MIDI 文件导入音符数据，并将其与波形一起显示。

可视化、比较和注释

该应用程序提供用于修改数据显示方式的选项。因此，您可以自由调整水平和垂直缩放级别，以便聚焦波形的任何区域并进行详细分析。

选择工具使您能够定义波形部分并更轻松地进行比较。为了方便起见，Sonic Visualiser 还可以将播放速度减慢到初始速度的 10%。

值得一提的功能之一是可以导入注释层（CSV、LAB、MID、TXT）并将其叠加在波形表示上。此外，它还配备了一组集成插件，可以自动计算注释，并考虑调音和音高。

探索音频文件的内容

Sonic Visualiser 使您能够探索并详细了解音频文件的结构，并提供高级注释选项，帮助您记录发现。它配备了丰富的工具集和选项，用于管理频谱数据和图层，支持音频播放和信号比较。

功能
• 加载 WAV、Ogg 和 MP3 格式的音频文件并查看其波形。
• 查看音频可视化效果，例如频谱图视图，并可交互式调整显示参数。
• 通过添加标记的时间点并定义片段、点值和曲线来注释音频数据。
• 使用对齐的刻度将注释叠加在一起，并将注释叠加在波形图或频谱图视图之上。
• 同时以多种时间分辨率查看相同数据（用于特写和概览）。
• 运行特征提取插件，使用节拍跟踪器、音高检测器等算法自动计算注释。
• 从各种文本文件格式导入注释层。
• 从 MIDI 文件导入音符数据，与其他频率刻度一起查看，并与原始音频一起播放。
• 播放音频和合成注释，注意播放与显示同步。
• 选择感兴趣的区域，可选择捕捉到附近的特征位置，并在无缝循环中试听单个和比较选择。
• 时间拉伸播放，可在保持同步显示的同时，减慢或加速至原始速度的一小部分或数倍。
• 将音频片段和注释层导出到外部文件。

新功能
• 改进了垂直刻度标注的位置和方式
• 更新了构建支持材料和文档，以反映 Cap'n Proto 0.6 的正式版本（我们现在可以使用该版本，而不必依赖 git 构建）。

操作系统：Windows XP / Vista / 7 / 8 / 10（32/64 位）

Sonic Visualiser is an open-source audio analysis and annotation utility that displays the waveform of a music file, enabling you to get an insight of what is behind the output sound.

Variate format support and importing capabilities

Mainly addressed to music technicians, it can display a graphical representation of the audio signal for each channel and annotate loaded data for easier identification of segments.

It aims to provide a user-friendly tool for displaying spectograms and audio waveforms, ensuring compatibility with some of the most common audio formats (such as WAV, MP3, AIFF, AVR, FLAC, OGG, RAW), as well as less popular file types (AU, CAF, HTK, IFF, MAR, MPC, PVR, RF64, SDS, W64, WVE, XI). Moreover, it enables you to import musical note data from locally stored MIDI files and display it alongside the waveform.

Visualization, comparison and annotation

The application features options for modifying the way data is displayed. As such, you can freely adjust the zoom level both horizontally and vertically, so as to focus on any area of the waveform and analyze it in detail.

The selection tools enable you to define waveform sections and compare them much easier. For your convenience, Sonic Visualiser can also slow down the playback to such an extent that it reaches 10% of the initial speed.

One of the worth-mentioning features is the possibility to import and overlay annotation layers (CSV, LAB, MID, TXT) on top of waveform representations. Furthermore, it comes with a set of integrated plugins that allow automatic calculations of annotations, taking into account tuning and sound pitch.

Explore the content of audio files

Sonic Visualiser enables you to explore and get close-ups on the structure of an audio file, providing advanced annotation options to help you write down your findings. It comes with a broad tool set and options for managing spectrum data and layers, allowing audio playback and signal comparison.

FEATURES
• Load audio files in WAV, Ogg and MP3 formats, and view their waveforms.
• Look at audio visualizations such as spectrogram views, with interactive adjustment of display parameters.
• Annotate audio data by adding labelled time points and defining segments, point values and curves.
• Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views.
• View the same data at multiple time resolutions simultaneously (for close-up and overview).
• Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on.
• Import annotation layers from various text file formats.
• Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio.
• Play back the audio plus synthesized annotations, taking care to synchronize playback with display.
• Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops.
• Time-stretch playback, slowing right down or speeding up to a tiny fraction or huge multiple of the original speed while retaining a synchronized display.
• Export audio regions and annotation layers to external files.

What's New
• Improve decisions about where and how to label vertical scales
• Update build support material and documentation to reflect the official release of Cap'n Proto 0.6 (which we can now use rather than depending on git builds)
