Copy the Sample Rate of Selected Audio File in Finder To Clipboard

Hey @JOSEPH_BRANCIFORTE ,

Here's one way to extract the sample rate off the first selected audio file in FInder:

/** @param {{ path: string }} arg */
function getSampleRateFromAudioFile({ path }) {
    /** @param {string} str */
    function escapeCharacters(str) {
        // There are more characters that need to be escaped
        // these are the most common I know of
        return str.replace(/([ *])/g, "\\$1");
    }

    const audioFileInfo = sf.system.exec({
        commandLine: `afinfo ${escapeCharacters(path)}`
    }).result;

    const match = audioFileInfo.match(/(\d{5,6}) Hz/);

    if (!match) throw "Could not read sample rate from this file.";

    const sampleRate = match[1];

    return sampleRate;
}

const sampleRate = getSampleRateFromAudioFile({
    path: sf.ui.finder.firstSelectedPath
});

log(sampleRate);

thanks @raphaelsepulveda & @Chris_Shaw... you guys are the best!

for whatever reason, raphael's script is not working for me ("Could not read sample rate from this file." every time), but chris's finder-based solution is!

although i imagine it is more robust to use the command line afinfo tool as in raphael's approach... so maybe we could try to troubleshoot that.

here is the finished script:

//// get the filepath & session type of selected session (currently supports pro tools & logic x)

sf.keyboard.press({
    keys: "cmd+option+c",
});

var session_path = sf.clipboard.getText().text;
var session_type = session_path.split('.').pop();


/// go to "audio files" folder at the same level as session.

var audio_folder_path = (session_path.substring(0, session_path.lastIndexOf("/")).concat("/Audio Files"));

sf.ui.finder.menuClick({
    menuPath: ["Go", "Go to Folder…"],
});

sf.wait({
    intervalMs: 200,
});

sf.keyboard.type({
    text: audio_folder_path,
});

sf.keyboard.press({
    keys: "enter",
});

sf.wait({
    intervalMs: 1000,
});

//// navigate to first file in "audio files" folder.

sf.keyboard.press({
    keys: "right",
});

sf.wait({
    intervalMs: 200,
});
