🚀 One-Click Install

For the vast majority of users, getting started is incredibly simple:

1. Double-click Setup.exe and you're done.
2. This one-time utility automatically creates desktop and local shortcuts that handle all administrator permissions for you. This provides a seamless, UAC-prompt-free experience every time you launch the application.

🍪 Using Cookies (Highly Recommended)

This step is often mandatory to help bypass anti-bot checks, access age-restricted content, and accept cookie banners.

1. Use an extension like "Get cookies.txt LOCALLY" to copy your browser's cookies.

   • For the most reliable cookies, first open a new Private/Incognito browser window.
   • Ensure the extension is allowed to run in this mode in your browser's settings.
   • Log into the desired website (e.g., YouTube) before exporting the cookies.

2. Import into ARN-DL: In the script's main menu, select "Manage cookies". Paste the copied text into the cookies.txt file that opens and save it.

🎵 The ARN Inside Audio Experience

ARN-DL is more than a tool; it's an experience. The custom audio ambiance, which features the "ARN Inside" brand name, is an integral part of this vision, designed to make every interaction memorable.

• Smart Audio Management: The audio is designed to be non-intrusive. It automatically pauses when you minimize the window and resumes when you return, allowing you to run silent downloads in the background while enjoying the unique atmosphere when interacting with the app.

📖 User Guide: The Download Flow

The script guides you through a series of menus to configure your download precisely.

1. Main Menu: After starting, you are presented with the main menu. Here, you can choose to:
   • Paste a single or multiple links.
   • Manage cookies (opens cookies.txt).
   • Access the Options menu.
   • Update the tools or the script itself.
2. Format Selection Menu: After providing a link, you'll be asked what you want to download:
   • Video: Downloads the video with its audio track in a single file (MP4 or MKV).
   • Audio Only: Downloads only the audio track and saves it as a high-quality .wav or .mp3 file.
   • VIDEO + SEPARATE AUDIO: Downloads the video file and also creates a separate, high-quality audio file.
3. Quality Selection Menu: Next, you define the quality:
   • Video Quality: Choose a maximum resolution, such as "High (Max 1080p)" or "Ultra (4k, 8k...)". The script will find the best available quality up to that limit.
   • Audio Quality: If you are downloading audio, choose between .WAV (lossless, highest quality) and .MP3 (high-bitrate, smaller file size).
4. Playlist Selection Menu: If you enter a link to a playlist, a final menu appears. It lists all the videos in that playlist, allowing you to:
   • Navigate through the list.
   • Select or deselect individual videos.
   • Press 'A' to select or deselect all videos at once.
   • Press 'V' to validate your selection and begin downloading.

⚙️ Core Mechanisms: The Technical Implementation

This section details the specific technical implementations that power ARN-DL, providing a look "under the hood" that the summary table cannot. This is the proof of how the script's features are achieved with a focus on resilience, quality, and user experience.

• Seamless UAC Bypass via Scheduled Task The "One-Click Install" is not a simple shortcut. The Setup.exe utility creates a Windows Scheduled Task configured to run the script with the highest privileges. The desktop shortcut then executes this task on demand (schtasks /run). This task has no automatic trigger and only runs when you click the shortcut, providing a secure and seamless method to gain the necessary permissions without recurring UAC prompts.

• Intelligent Format Selection via Opinionated Sorting Instead of a simple format request, the script uses yt-dlp's powerful sort flag (-S) to enforce a quality hierarchy. For audio, the sort key 'hasaud,+codec:opus,abr,+ext:m4a,abr,quality' prioritizes Opus audio streams, falling back to AAC (ext=m4a) only if Opus is unavailable. This ensures the best available audio codec is always chosen automatically.

• Client Emulation via Iterative Retries To bypass device-specific quality restrictions by emulating various clients (phone, TV)restrictions, the script maintains a list of client profiles (e.g., web, ios, android_tv). When a download fails, it programmatically iterates through this list, re-issuing the same download request with a different client identity header on each attempt. This methodical loop turns a single point of failure into multiple opportunities for success.

• Exhaustive Brute-Force via a Test Matrix This mode programmatically generates a test matrix of possibilities. It builds a "cascade" of format strings for every resolution, then enters a nested loop: for each format, it attempts a download using every single client profile. This systematic search (Formats x Clients) guarantees that if a working combination exists, the script will find it.

• Windows-Compatible WAV Metadata Generic metadata commands often create .wav files that are unreadable by Windows Explorer. To solve this, the script manually reconstructs the RIFF file structure. It reads the file byte by byte, isolates the fmt and data chunks, and writes a new file with a correctly formatted LIST INFO chunk, ensuring universal compatibility.

• Responsive UI with a Non-Blocking Input Loop The UI remains fluid thanks to a custom Wait-KeyNonBlocking function. Instead of freezing while waiting for input, it runs a high-frequency loop that checks for key presses ([System.Console]::KeyAvailable) while simultaneously updating background animations, creating a responsive, "asynchronous-style" experience.

• Flicker-Free Console Rendering The smooth animations are achieved with a double-buffering technique. For each frame, the script builds the next scene in an in-memory array, compares it to the previous frame, and then surgically updates only the characters that have changed, eliminating flickering.

• Advanced Playlist Management with Pagination To handle massive playlists without overwhelming the UI, the script implements a custom pagination system. The Show-PlaylistSelectionMenu function slices the full video list into manageable pages of 20 items using PowerShell's Select-Object -Skip/-First cmdlets. It maintains a persistent list of selected indices that works across all pages, allowing the user to navigate with arrow keys, make granular selections, and select/deselect all, providing complete control over playlists of any size.

🛠️ Advanced & Manual Installation

Manual Shortcut Creation (Alternative Method)

This section is for advanced users or for those who encounter issues with the standard Setup.exe installer.

• Important Trade-off: Using this manual method will cause Windows to show a UAC (administrator approval) pop-up every time you launch the script. The standard installation method avoids this.

1. Navigate to the Script Folder: Open the main application folder and go into the Data_Inside directory.

2. Create a Shortcut to Desktop:

   • Locate the ARN-DL.ps1 file. Right-click on it.
   • Note for Windows 11 users: You may need to click "Show more options".
   • Go to "Send to" and then select "Desktop (create shortcut)".

3. Configure the Shortcut Properties:

   • Go to your desktop, find the new shortcut, right-click on it, and choose "Properties".
   • In the "Shortcut" tab, locate the "Target" field. You must replace its entire content with the command below.
   • Copy and paste the following full command into the "Target" field, which includes an example path:

     C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoExit -ExecutionPolicy Bypass -NoProfile -File "C:\Users\YOUR_USER_NAME\...\Data_Inside\ARN-DL.ps1"
     

   • CRITICAL: You must now manually edit the example path to match the exact location of your ARN-DL.ps1 file.

4. Set Administrator Privileges:

   • While still in "Properties", click the "Advanced..." button.
   • Check the box for "Run as administrator" and click "OK".

5. Apply and Finish: Click "Apply" and then "OK". You can now rename the shortcut to "ARN-DL".

✍️ A Note from the Author: Project Philosophy

ARN-DL is a labor of love, freely offered to the community after two months of hard work. Considerable effort was expended to create not only a functional tool, but also a unique user experience, striving for "divine perfection"! The musical and aesthetic choices are a deliberate tribute to the monumental work of Terry A. Davis, reflecting the creative ambition of the project:

Terry A. Davis built an entire operating system by himself, a digital temple born from a revelation. Imagine his creative power, augmented by cloud AI, if he were still with us today.

About the integrated audio and author signature

The audio experience is an integral part of ARN-DL's design and brand identity. To preserve this vision, the script includes an author's signature that verifies the integrity of the core audio components. This feature is also a cultural "easter egg." As this project is fully open-source, the code can naturally be modified. This signature therefore acts not as a technical barrier, but as a clear statement of authorial intent and a safeguard for the project's artistic identity.

This project is shared under the GPLv3 license, which grants you extensive freedoms to modify and share the code. However, the spirit of open-source is collaboration and improvement. Redistributing a modified version where the sole change is the removal of the project's identity and artistic signature, without adding any other value, is contrary to this spirit. I ask that you respect the original work and authorship.
