f1radio

F1 team radio clips with full race context. Built on OpenF1.

Load any session from 2023 onwards — every radio clip comes enriched with position, tyres, gaps, flags, overtakes, and pit stops. Everything is cached locally so you only hit the API once.

Installation

pip install f1radio

Optional extras for audio playback and transcription:

pip install 'f1radio[playback]'       # audio playback
pip install 'f1radio[transcribe]'     # whisper transcription (coming soon)
pip install 'f1radio[all]'            # everything

Note: If you're using zsh (default on macOS), you need quotes around the brackets — 'f1radio[playback]' instead of f1radio[playback].

Requirements: Python 3.9+. No API keys needed.

Quick Start

import f1radio

# load a session — race names are fuzzy matched
session = f1radio.load(2024, "Monza", "R")

# browse clips
for clip in session.clips:
    print(f"{clip.driver} | Lap {clip.lap} | P{clip.context.position} | {clip.context.compound}")

# filter by driver
for clip in session.clips.filter(driver="VER"):
    print(clip)
    clip.play()  # requires playback extra

# export
session.export_json("monza_radio.json")
session.export_csv("monza_radio.csv")

Race name matching is flexible — "Monza", "Italian", "Italy", "Italian Grand Prix" all resolve to the same session.

What You Get

Every clip is enriched with what was happening at that exact moment:

Field	Example	Description
position	1	Driver's position
gap_to_leader	"+1.432"	Gap to P1
compound	"SOFT"	Current tyre
tyre_age	12	Laps on current set
lap_number	14	Current lap
events	["SAFETY CAR"]	Flags/events within ±30s
overtakes	["VER → NOR for P2"]	Nearby overtakes
pit_stops	["HAM pitted"]	Nearby pit activity

clip = session.clips[0]
ctx = clip.context

print(ctx.position)       # 1
print(ctx.compound)       # "SOFT"
print(ctx.tyre_age)       # 12
print(ctx.events)         # ["YELLOW FLAG - Turn 4"]

CLI

f1radio download 2024 Monza R     # download and cache a session
f1radio info 2024 Monza R         # show session metadata
f1radio cache list                # see what's cached
f1radio cache clear               # clear everything

Caching

Sessions are cached after first load — subsequent calls are instant with zero API requests. Cache is cleaned up automatically after 30 days of inactivity.

f1radio.cache_info()       # see cached sessions and sizes
f1radio.clear_cache()      # wipe everything

API Responsibility

Built to be a respectful consumer of the OpenF1 API:

• Rate limited — 2.5 req/sec, 28 req/min (under the API's limit of 3/s)
• Circuit breaker — stops after repeated 429s to avoid bans
• Conditional requests — ETag headers to skip unchanged data
• Transparent — f1radio.stats shows exactly how many API calls were made

Supported Sessions

R	Race
Q	Qualifying
S	Sprint
SQ	Sprint Qualifying
