Tips for improving audio quality in Android Auto

Cable Quality and Connection Stability

A functional cable supporting Android Auto will not improve audio quality by upgrading to a higher bandwidth cable. While a faulty cable can cause disconnections, additional bandwidth does not enhance an already stable digital audio stream. Google recommends high-quality cables for basic troubleshooting of connection issues, not for audio fidelity improvements.

Optimizing Music App Settings

Users should first examine their music app settings. Weak cellular connections can degrade streaming quality, so pre-downloading playlists or albums can eliminate this factor. Apps like Spotify and YouTube Music offer settings to adjust streaming and download quality based on network conditions or user preference. Setting a higher download quality is recommended, but maximizing all numbers may not always result in better sound, as Android supports playback sample rates up to 192kHz, but a universal Android Auto output rate is not confirmed.

Adjusting EQ and Normalization

Equalizer (EQ) and normalization settings significantly impact in-car audio. An EQ profile designed for earbuds with bass boost can sound distorted in a car's different speaker configuration, especially if the car also applies its own audio processing. Spotify's Loud normalization setting, which includes a limiter, can also affect sound. It is advised to temporarily flatten the EQ, set normalization to Normal or off, and then reintroduce adjustments incrementally to identify optimal settings.
