TEMPO：在動畫 GIF/PDF/SVG 中播放聲音

練琴的時候，速度（iOS 上的應用程序，CHplay）是一個節拍器，通常用於按時節拍。

我可以為 TEMPO 製作動畫 GIF/PDF/SVG/frame（在 中beamer），但不知道如何播放聲音（例如 beep 8，mp3或wav在這裡）在每個節拍。

任何人都可以幫忙（提供完整的程式碼和清晰的解釋）嗎？謝謝你！

在此輸入影像描述

以下程式碼是我的 MWE。 （這些是動畫事物的好例子）

% TEMPO for piano tempo.tex
% for animated GIF, run on command line (require ImageMagick installed)
% magick -density 200 -delay 100 tempo.pdf tempo.gif
% -delay 100 >>> each frame is 100/100 = 1 second 
\documentclass[tikz]{standalone}
\begin{document}
\foreach \n in {1,...,4}{
\pagecolor{white}
\begin{tikzpicture}
\path (0,-1) rectangle (5,1);
\shade[inner color=green,outer color=green!10] 
(\n,0) circle(.5);
\foreach \i in {1,...,4}
\fill[cyan] (\i,0) circle(.3);
\end{tikzpicture}
}
\end{document}

只需稍作修改，我們就可以獲得動畫 PDF（在 Acrobat Reader 中開啟）。

% animated PDF standalone tempopdf.tex
% \multiframe{4}{n=1+1} >>> starting frame is with n=1, 
% then plus 1 each frame, so we have 4 frames
% [loop,controls]{1} >>> number 1 means 1 second each frame
\documentclass{standalone}
\usepackage{tikz}
\usepackage{animate}
\begin{document}
\begin{animateinline}[loop,controls]{1}
\multiframe{4}{n=1+1}
{
\begin{tikzpicture}
\path (0,-1) rectangle (5,1);
\shade[inner color=green,outer color=green!10] 
(\n,0) circle(.6);
\foreach \i in {1,...,4}
\fill[cyan] (\i,0) circle(.3);
\end{tikzpicture}
}
\end{animateinline}
\end{document}

\foreach \i in {1,...,4} \fill[cyan] (\i,0) circle(.3);
\end{tikzpicture}
}
\end{animateinline}
\end{center}
\end{frame}

點選在下圖中查看正在運行的滴答節拍器（SVG 版本）：

https://agrahn.gitlab.io/svg/tempoForWeb-2.1.svg

這個animate基於 的範例有兩個版本。

這PDF版本需要 Acrobat Reader，因此僅限於桌上型電腦的 Windows 和 OSX 平台。 （不支援行動裝置。） PDF 版本用於media9播放嵌入的聲音文件click.mp3，取自animate軟體包，該軟體包已在其手冊中提供了滴答作響的節拍器範例。

獨立式靜止無功發生器版本可以在大多數現代網頁瀏覽器（Firefox、Chrome、Opera ...）中運行，甚至可以在行動裝置上運行。此處，聲音使用 HTML5<audio>標籤嵌入為 Base64 編碼的 Blob。 （在命令列上click.mp3以「」編碼base64 click.mp3。）物理嵌入的聲音檔案使 SVG 獨立。

無論哪種情況，JavaScript 都會在執行動畫的每個畫面變更時開始播放聲音。的“時間軸”特性animate用於將JS代碼與每一幀（時間軸輸入frames.txt）關聯起來。

速度標記是在第二animateinline環境中實現的。它提供 39 種典型的節拍器速度，可以使用 +/- 按鈕進行步進。這些按鈕利用animateJavaScript 介面來增加並減少速度標記影格編號。另一個時間軸檔案 ，tempo.txt將每個標記幀與一個 JS 片段相關聯，該片段相應地縮放節拍器速度，同樣使用animate.

獨立、動畫動圖是又聾又啞，據我所知，似乎不存在一種易於訪問的方法來同步嵌入的 Gif（在網頁中）與聲音。但靜止無功發生器優越得多，因為它是向量的，因此可以自由擴展。

答案2

您也可以在其他地方用聲音製作動畫並將其添加到 Beamer 檔案中。 Beamer 似乎有一個多媒體包。 movie15 似乎也很有希望。

看看這個關於多媒體/聲音的帖子如何在 PDF 中包含音訊文件，也許這是一個有效的起點。
