DESCRIPTION:  In the aftermath of heavy ion collisions\, a deconfined stat
 e of matter known as the Quark-Gluon Plasma (QGP) is formed. One of the mo
 st extensively studied effects arising from the presence of a medium is je
 t quenching\, which refers to the energy loss experienced by jets as they 
 traverse the QGP. This energy loss is primarily driven by medium-induced i
 nteractions that stimulate the emission of partons at large angles. These 
 emitted partons are ultimately detected outside the jet cone\, leading to 
 the observed suppression of jet energy. As the precision of jet-quenching 
 observables continues to improve\, the need for more precise analytical to
 ols to accurately describe in-medium gluon emissions has become increasing
 ly critical.This work focuses on the theoretical description of medium-ind
 uced emissions within the framework of the BDMPS-Z formalism. Building on 
 recent developments\, we extend previous results for the emission spectrum
  of single medium-induced radiation\, which had been restricted to the sof
 t regime. We derive a more generalized expression for the emission spectru
 m\, without relying on the harmonic or single hard approximations\, and de
 monstrate that this expression reduces to the established result in the so
 ft limit.Additionally\, to facilitate further research\, we provide a comp
 utational routine based on a set of differential equations\, designed to s
 implify the evaluation of the spectrum by avoiding cumbersome numerical in
 tegrations. Lastly\, we illustrate the application of this routine through
  the use of the large    approximation.
