Upload the audio file you wish to embed on your blog onto your web server or a free file-hosting website. Blogger does not support audio file uploads. You need to store the file on your personal web server or on a file-hosting website.
Log in to Blogger.
Click “New Post.”
Click the “Edit HTML” tab.
Copy and paste the following code for the Google audio player into the input area, replacing [AUDIO FILE URL] with the address location of the audio file you uploaded in the first step.
Click the “Compose” tab and complete the blog post according to your preference. Click “Publish Post.” The audio player will be embedded within the body of your Blogger post.
