A few years ago somebody uploaded the song Jolene by Dolly Parton that was played on a record player at 33rpm instead of the intended 45rpm, you can listen to that song on YouTube by clicking here.
The song gained a lot of attention online as many people thought it sounded as good as, if not better than the original. I thought what other songs would sound good at 33rpm, hence the inspiration for this project.
I also haven’t built a project yet using ChatGPT, so for this simple project I said I would build the entire thing using nothing more than prompts on Bing chat which is powered by ChatGPT 4.
Im also very well aware that you can watch a music video on YouTube or on any media player and set the speed to a slower speed to achieve the same effect. This project was not about building a new technology. It was about seeing how i could build a simple project using nothing more than prompts on Bing chat with little or no coding from me as the developer.
The full conversation with bing chat and all of the prompts, replies and code generated can be found in section 9 of this document. My summary on the project can be read in section 10.

1. User Experience (UX)
Anyone who wishes to hear one of their favourite songs played at 33rpm.
As a visitor to The 33RPM Player I want to be able to upload a song and hear it played at 33rpm.
As a visitor to The 33RPM Player want/expect/need:
- A simple user interface that is easy to navigate.
- To be able to upload a song and hear it played at 33rpm.
- To be able to fast forward and rewind the song.
- To be able to see the name of the song that is playing.
- To be able to see an error message if i try to upload a file that is not an audio file.
As i made this project completely using prompts in Bing chat i decided i would not make any design choices in advance and decide on the design choices as i go.
COLOURS
I would prompt Bing chat with different requests as the project progressed and see what colour schemes the chat bot could come up with as we went through the CSS part of the project.
2. Features
The clearly marked drop zone is where desktop users must drag the audio file they wish to listen to at 33rpm.
For mobile users who don't have drag and drop functionality, they can click on the upload file button and select the audio file they wish to listen to at 33rpm.
A standard HTML player that Bing chat generated when i gave it the prompt.
The fast forward and rewind buttons are standard HTML buttons that Bing chat generated when i gave it the prompt. The Javascript behind them allows users to skip forward or backwards by 10 seconds per click. All of the Javascript functionality was generated by Bing chat when i gave it the prompt.
The song/file name is displayed to the user after the player loads it.
If the user tries to upload a file that is not an audio file they will be presented with an error message.

9. Prompts and code
Below you can see the entire conversation i had with Bing chat to build this project. The prompts i asked and the responses Bing chat gave me.
Prompt 1:
I want to build a website where users can drag an audio file and an audio player will play the song back at 33rpm. Let’s discuss the tech stack needed to do this
Response
Sure! To build a website with the functionality you described, you’ll need to use a combination of front-end and back-end technologies. For the front-end, you can use HTML, CSS, and JavaScript to create the user interface and handle user interactions such as dragging and dropping an audio file. For the back-end, you can use a server-side language such as PHP or Node.js to process the audio file and play it back at 33rpm. You’ll also need a web server such as Apache or Nginx to host your website.
Is there a specific technology or language you prefer to use?
1 of 24
Prompt 2:
The user won’t be able to store any music, they will only be able to drag and drop 1 song at a time, so no need for any backend
Response
In that case, you can build the website using only front-end technologies. You can use HTML, CSS, and JavaScript to create the user interface and handle user interactions such as dragging and dropping an audio file. You can also use JavaScript to process the audio file and play it back at 33rpm using the Web Audio API.
Do you have any experience with these technologies?
2 of 24
Prompt 3
Yes I have experience with these. Can you generate the html code for me?
Response
Sure! Here’s a basic HTML template that you can use as a starting point for your website:
<!DOCTYPE html>
<html>
<head>
<title>Audio Player</title>
</head>
<body>
<h1>Audio Player</h1>
<p>Drag and drop an audio file here:</p>
<div id="dropzone" style="width: 300px; height: 100px; border: 2px dashed #ccc;"></div>
<audio id="player" controls></audio>
<script>
// Your JavaScript code goes here
</script>
</body>
</html>
Preview of player generated
This template includes a dropzone element where users can drag and drop an audio file, and an audio element to play the file. You’ll need to add your own JavaScript code to handle the drag and drop event and play the audio file at 33rpm.
Is there anything else you need help with?
3 of 24
Prompt 4
OK, now let’s write the JavaScript. When the user drags and drops a song into the player I want the song to start playing at 33rpm automatically. Generate this JavaScript code for me and add it to the html file you generated previously.
Response
Sure! Here’s the updated HTML template with the added JavaScript code to handle the drag and drop event and play the audio file at 33rpm:
<!DOCTYPE html>
<html>
<head>
<title>Audio Player</title>
</head>
<body>
<h1>Audio Player</h1>
<p>Drag and drop an audio file here:</p>
<div id="dropzone" style="width: 300px; height: 100px; border: 2px dashed #ccc;"></div>
<audio id="player" controls></audio>
<script>
// Get the dropzone and player elements
const dropzone = document.querySelector('#dropzone');
const player = document.querySelector('#player');
// Handle the dragover event
dropzone.addEventListener('dragover', (event) => {
event.preventDefault();
});
// Handle the drop event
dropzone.addEventListener('drop', (event) => {
event.preventDefault();
// Get the dropped file
const file = event.dataTransfer.files[0];
// Create a file reader
const reader = new FileReader();
reader.onload = (event) => {
// Set the audio source and play the file at 33rpm
player.src = event.target.result;
player.playbackRate = 0.5;
player.play();
};
reader.readAsDataURL(file);
});
</script>
</body>
</html>This code adds event listeners to the dropzone element to handle the dragover and drop events. When a user drags a file over the dropzone, the dragover event is fired and the default behaviour is prevented. When a user drops a file onto the dropzone, the drop event is fired and the dropped file is read using a FileReader. Once the file is read, its data is set as the source of the audio element and played back at 33rpm using the playbackRate property.

This code adds two new button elements with the ids of rewind and fastforward to allow users to rewind or fast forward the audio by 10 seconds. When a user clicks on one of these buttons, the currentTime property of the audio element is updated to move the playback position backward or forward by 10 seconds.

Prompt 9
Is there a way we can check if the user is dropping or uploading a none audio file? If so how do we check this? And if it’s not an audio file that the player can play, can we generate a message to the user to say "Sorry the type of file you are trying to load cannot be played in this player"
Response
Yes, it is possible to check if the user is dropping or uploading a non-audio file. You can do this by checking the type property of the dropped or selected file to see if it starts with audio/. If the file is not an audio file, you can display a message to the user to let them know that the file cannot be played.

Prompt 11
If the user drags an audio file and drops it outside of the dropzone then the song will open in a new tab in the browser and play at normal speed. Can we disable this so if the user drags and drops a file outside of the dropzone nothing happens
Response
Yes, it is possible to prevent the default behavior of the browser when a user drags and drops a file outside of the dropzone. You can do this by adding an event listener to the document object to handle the dragover and drop events and prevent their default behavior.
Here’s the updated HTML template with the added code to prevent the default behavior of the browser when a user drags and drops a file outside of the dropzone:

Can we change the html and CSS so on desktop computers the fast forward and rewind buttons are side by side on the same row. And on mobile devices they change to be stacked on top of each other. The breakpoint to enable this change is 786px

10. Project summary
At this point i could do more CSS to give the player a better aesthetic look, however, i wanted to use this project to demonstrate how you could take an idea and build a fully functioning project of HTML, CSS and Javascript using as little as 24 prompts using Bing chat.
Functionality
The players functionality does exactly what i asked Bing chat for. All of the code that was generated was done so will no errors and it functioned exactly how i wanted it to. I did need to expand on one or two requests to get it exactly how i wanted, but the functionality works the way i requested.
Design and aesthetics
For me Bing chat is still lacking in the CSS and design space. When i asked it for a few colour schemes originally the green and brown versions it came back with very not pleasant to look at. I had to prompt it to try the blue/lavender. Also the final colour scheme of dark grey and bright green came from me the developer as a prompt.
Im sure i could probably make this much more aesthetically pleasing if i used more prompts, but the whole idea behind this project was to get a MVP (Minimum Viable Product) published in as few prompts as possible.
Ive no doubt as the ChatGPT/Bing chat technology develops the design and aesthetics will improve, but for now it is lacking in this area.
Development time
This is where Bing chat really did show what its capable of, this entire project was completed in around 15 minutes from my first prompt right through until my 24th prompt.
Code summary
HTML: 37 Lines of code
CSS: 65 Lines of code
Javascript: 89 Lines of code
Total lines of code: 191
Final thoughts
I think this project really shows the power and potential of ChatGPT/Bing chat. Any experienced developer reading this might think its a simple easy project and i could do it in my sleep.
However what i wanted to demonstrate with this project was how someone with little or no coding experience could leverage the power of Bing chat/ChatGPT and take a project from concept to completion in as little as 15 minutes.
As well as being a junior software developer im also an entrepreneur and business owner. I meet so many people with great business ideas who sometimes don't have the necessary funding or technical expertise to develop their ideas into products.
As long these AI tools remain free/minimum cost, this barrier to entry is a barrier i can see being broken down dramatically which i think is a good thing.
