For years, the eFootball Pro Evolution Soccer (PES) series has been celebrated for its superior gameplay mechanics, realistic ball physics, and tactical depth. However, one area where the series has historically lagged behind its competitors is in audio presentation—specifically, stadium chants, crowd reactions, and ambient noise.
Enter the Eternity Audio Tool for PES 2021. This third-party software has become a legendary piece of kit within the modding community, bridging the gap between Konami’s vanilla soundscape and the thunderous, spine-tingling reality of a live football match. If you have ever felt that your virtual Anfield, San Siro, or Signal Iduna Park sounds like a library, this tool is your megaphone.
In this article, we will dissect what the Eternity Audio Tool is, why it is essential for any serious PC PES 2021 player, how to install it, and where to find the best chant packs.
Step 1: Download the Tool
Visit EvoWeb Patches or the official Eternity thread on PESModding. Download the latest Eternity_Audio_Tool_KE.zip. Avoid sketchy third-party re-uploads that might contain malware.
Step 2: Extract to a Permanent Folder
Extract the contents to a folder like C:\PES2021\EternityAudio. Do not put this inside your Sider folder. Keep it separate. eternity audio tool pes 2021
Step 3: Locate your PES Audio Files Inside the tool, you will need to point it to:
Step 4: Run the Tool in Admin Mode
Right-click EternityAudioTool.exe -> Run as Administrator. The interface looks intimidating—a series of tabs, hex values, and waveform graphs. Do not panic.
Step 5: Load a Sound Mod
Most users will not build chants from scratch. Instead, download a pre-made sound pack (see section below). Look for a .eat project file or a folder structure containing chant_*.wav files.
Step 6: Integration with Sider To activate the tool before launching PES: For years, the eFootball Pro Evolution Soccer (PES)
Step 7: In-Game Testing Go to Exhibition Mode. Pick a team with a custom chant pack. Listen carefully. You should hear your custom audio instead of the generic loop.
Open the Config.ini file with Notepad. You must map your chant folders to PES’s internal team IDs. For example:
A full list of team IDs can be found in the Team.bin file or via the PES Master Database website.
You can assign a specific .wav file to play after a goal. In the Bundesliga, this is iconic (e.g., Borussia Dortmund’s “You’ll Never Walk Alone” horn). For English stadiums, add the generic “GOAL!” announcement from the PA system. Step 1: Download the Tool Visit EvoWeb Patches
One major question: Will my FPS drop?
The Eternity Audio Tool is remarkably lightweight. It uses less than 2% CPU and about 150MB of RAM when streaming uncompressed WAV files. The KE Server runs on a separate thread, meaning it does not interrupt the game’s render pipeline.
However, if you have a mechanical HDD (not an SSD), loading 500+ high-fidelity chants simultaneously can cause a 1-2 second audio stutter during kickoff or corner kicks. Recommendation: Install PES 2021 and all audio mods on an NVMe SSD or SATA SSD for seamless streaming.
Open the Config.ini and set DisableGenericChants=1. This ensures that only your custom chants play. No more hearing the same “Olé, olé” loop for Stoke City and PSG.
