Twenty songs (four from each genre choir, opera, orchestra, pop, and schlager) were used from the audio corpus described in the first experiment.

Dynamic range compression (often shortened to just “compression”) is a process that limits the volume range of a piece of music. Even for classical music, a string quartet, for example, would have a narrow dynamic range and the clarity of each instrument would be more prominent. Listeners might be more sensitive to distortion introduced by compression in music than in speech. To limit this potential bias, controls were put in place so that within each band, the same gain was applied (on average) in the linear, semicompressive, and compressive setting. Music compression is the process of reducing a signal’s dynamic range. For rock and pops on the other hand, spaciousness is not as necessary as for classical music, and so there is greater emphasis on clarity than spaciousness. The authors disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The research protocol for this study was approved by grant (KEK-ZH. The linear condition was rated loudest (56.81), followed by the semicompressive (51.35) and the compressive condition (47.94). The linear condition was rated highest in quality (60.53) followed by the semicompressive (54.30) and the compressive condition (47.43; Figure 7). Dynamic range compression serves different purposes in the music and hearing-aid industries. Understanding dynamic range "Understanding dynamic range is essential to achieving a good sound. A CD made to be heard this way can sound really bad on a proper hi-fi, lacking dynamic range. We further controlled the loudness of all stimuli with the dynamic loudness model (DLM) by Chalupper and Fastl (2002). Music segments were played back in stereo via two loudspeaker pairs in 1.2 m distance at an angle of 30° and −30°, as common practice in audio engineering (Dickreiter, Dittel, Hoeg, & Wöhr, 2014). To be clear, we're not saying that the above example is problematic per se.

Thus, by means of technology employed for commercial gain rather than in the service of musical experiences, we are acclimatised to pseudo-music with almost no dynamic range.

Dynamic compression introduces distortion (Kates, 2010). (. Each loudspeaker pair consisted of a mid- to high-range speaker (Meyer Sound MM-4-XP) and an aligned subwoofer (Meyer Sound MM-10-XP). So I am wondering how this seemingly modest figure of 26-28dB of dynamic range for a recording regarded as extreme stacks up against the theoretical maximum of the CD medium which is 98dB. Two of the most prominent composers of the Classical era, Joseph Haydn (1732–1809) and Wolfgang Amadeus Mozart (1756–1791), wrote harpsichord music. There is a secondary finding from the analysis of compression in recorded music that is also worth noting. Piano is the word we use to describe quiet or soft in music . The analysis revealed that the effect of order was not significant, F(1.2, 38.5) = 2.562, p = .120. Figure 4. the site you are agreeing to our use of cookies. f or forte, meaning "loud or strong". Allocation of participants to the two groups was controlled in a manner that minimized differences in age, hearing loss, or music experience. You need to reduce the dynamic range of most audio signals for them to sound natural on a recording. In the hearing-aid industry, it is used to map the variable dynamic range of acoustic signals to the re … The compression ratio of the semicompressive condition (CRsemi = Δgain/Δinput) is half the compression ratio of the compressive condition (CRcomp = 2 * Δgain/Δinput). Analog-to-digital conversion to accommodate the dynamics of live music in hearing instruments. Car radios therefore have to operate within a restricted dynamic range.

They listened to the semicompressed versions of the music segments and rated them on an absolute three-step scale (−1: do not like, 0: neutral, 1: like). In this comparison, live music consumption would account for less than 4% of total music consumption. Streaming services could potentially incorporate information about the dynamic range so that the hearing aids can optimize the compression accordingly. Participants were freely able to switch between channels (stimuli) at any given time. 3. The quality of the linearly processed stimuli was judged to be best, followed by the semicompressive and the compressive setting. View or download all content the institution has subscribed to.
