This paper examines the informal digital infrastructure through which Kenyan DJs acquire sound effects for live and recorded mixes. Drawing on interviews with 15 DJs in Nairobi (2023–2024), we map the primary download sources: YouTube ripping, Telegram channels, WhatsApp groups, and international sample packs. We argue that the reliance on pirated or repurposed Western SFX (e.g., airhorns, snare rolls) contrasts with a growing movement toward locally recorded sound effects using field recordings from matatus, markets, and political rallies. The paper contributes to debates on postcolonial digital labor, copyright evasion, and sonic identity in East African electronic music.
