## Describe the problem/error/question Hi there, in a workflow I need to send audio files to OpenAI Whisper to transcribe them. But sometimes, the files I receive are larger than the 25 mB limit. Do you know what would be the simplest way to split an audio file in smaller files in n8n? ## Information on your n8n setup - **n8n version:** 1.67.1 - **Database (default: SQLite):** Postgres ---

It looks like your topic is missing some important information. Could you provide the following if applicable. - **n8n version:** - **Database (default: SQLite):** - **n8n EXECUTIONS\_PROCESS setting (default: own, main):** - **Running n8n via (Docker, npm, n8n cloud, desktop app):** - **Operating system:** ---

In what format is your audio file to be split? ---

Hi @mredodos, the file extension is mpga and the Mime type is “audio/mpeg” ---

So i think you have 2 way 1 is with ffmpeg library, but you need to install it on the server/container and activate and use via execute command or you can try with cloud convert api ---

Thanks I will look at those two solutions. Ideally, I’d like to have no additional cost so I will go first with the library solution. ---

OK so I found a solution with ffmpeg library thanks to you @mredodos! If someone finds this topic here’s how I did it: - Add ffmpeg to n8n: I deploy it using Docker, so in the Dockerfile I added “RUN apk add --update ffmpeg” - In my workflow I write the binary file on the disk using the “Read/Write Files from Disk” node - Then I add an “Execute Command” node and execute the following command: `ffmpeg -i my_input_file.mp3 -f segment -segment_time 2400 -c copy split_audio_file_%03d.mp3` (Here I cut the file in 40 minutes segments and name the outputs “split\_audio\_file\_000.mp3”, “split\_audio\_file\_001.mp3”, etc.) - Then I can get the binary files by reading the disk and looking for files named “split\_audio\_file\_???.mp3” ---
