add btn to change speed of the audio

[daisukedd]

Description:

Currently, to change the audio speed, it is necessary to click on the three dots of the web file. 🎧 This can be a bit inconvenient for users who want to adjust the speed frequently. 🔄 I would like to suggest adding a more accessible button that allows selecting the audio speed more quickly and easily. 🚀

Requirements:

• Add a visible button to the main interface of the audio player. 🎛️
• The button should allow the user to select from various playback speeds (e.g., 0.5x, 1x, 1.5x, 2x). ⏩⏪
• The design of the button should be intuitive and consistent with the rest of the user interface. 🎨
• The speed change should be applied instantly to the playing audio. 🎶

Benefits:

• Improved usability of the audio player. 👍
• Convenience for users who need to adjust the audio speed frequently. ⚡
• A more efficient and pleasant user experience. 😊

Expected Behavior Example:

• The user sees the speed selection button on the main interface of the audio player. 👀
• The user clicks the button and chooses the desired speed. 🖱️
• The audio speed is immediately adjusted according to the user's selection. 🔊

Notes:

• Ensure that the new button does not interfere with other audio player functionalities. 🛠️
• Test the new functionality on different browsers and devices to ensure compatibility.
