Audio Support

Here we show how irouter makes audio queries as simple as text, image and PDF queries.

There are a limited amount of models that support audio input. Make sure to use an LLM that supports audio input, like google/gemini-2.5-flash.

To check which LLMs support audio input, check the OpenRouter Model Overview.

Local Audio Files

The simplest way to work with audio files in irouter is to pass the filepath and an instruction as a list of strings. Both .mp3 and .wav files are supported.

from irouter import Call

model_name = "google/gemini-2.5-flash"
audio_path = "../assets/bottles.mp3"

c = Call(model_name)
c([audio_path, "What do you hear?"], temperature=0)
# 'I hear the sound of a glass bottle being opened and closed, along with the distinct clinking of glass.'

Chat with Audio

Use Chat for conversation tracking and token usage monitoring:

from irouter import Chat

chat = Chat(model_name)
chat([audio_path, "What do you hear?"])
print(chat.history)
print(chat.usage)
