We provide a detailed description of the formalism, discuss suitable truncation schemes for real-time calculations, as well as the numerical procedure to self-consistently solve the flow equations for the spectral function. Subsequently, we discuss the relations to other perturbative and nonperturbative approaches to calculate spectral functions and present a detailed comparison and benchmark in <math><mi>d</mi><mo>=</mo><mn>0</mn><mo>+</mo><mn>1</mn></math> dimensions."
