In this comparison, live music consumption would account for less than 4% of total music consumption. Ideally, the compression parameters would adapt to individual songs or even adapt within a song. Yes, although there is a school of using only two microphones and no processing. ,{i:'fig5-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig5.gif',l:'10.1177_2331216516630549-fig5.jpeg',size:'401 KB'}]} ,{i:'fig4-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig4.gif',l:'10.1177_2331216516630549-fig4.jpeg',size:'341 KB'}]} An ANOVA was carried out with condition (linear, semicompressive, compressive) and genre (choir, opera, orchestra, pop, schlager) as within-subject factors. Hockley, N. S., Bahlmann, F., & Fulton, B. The compression ratio of the semicompressive condition (CRsemi = Δgain/Δinput) is half the compression ratio of the compressive condition (CRcomp = 2 * Δgain/Δinput). Recordings with insanely wide dynamic range. Furthermore, perceptual differences between the conditions varied across genre. Add to that the 96dB dynamic range and the peak output level from your speakers would need to be 136dB to experience the full dynamic range from a CD. The concluding point of the discussion is that Classical music is hard to define. As a consequence, multiband dynamic compression can change the level of each band independently and therefore also modify the spectral shape of a signal (Chasin & Russo, 2004). The recordings were equalized before further processing to compensate for the ear resonance of the KEMAR and the frequency response of the Sennheiser HD 600 headphones that were used for playback in the test sessions. Dynamics was explained as the difference between loud and soft passages. This site uses cookies. As with the original analysis, the differences in the linear condition were highest (3.75), followed by the semicompressive (2.90) and the compressive condition (−0.16).

For systems dedicated to classical music or extremely dynamic content, consider lowering the compression to a range between 1.5 and 2.0 to 1. All in one place. Someone tried to vandalise the database by deleting about 76k entries. Although loudness was well controlled in the experiment, we additionally asked participants to compare the loudness of the test stimuli across conditions. On the basis of the mere-exposure effect (Bradley, 1971; Gordon & Holyoak, 1983; Ishii, 2005; Szpunar, Schellenberg, & Pliner, 2004; Zajonc, 1980), we would expect a bias toward the compressive scheme that participants had grown accustomed to during the acclimatization period. It may be that benefit would be gained by setting the compression curves differently for each of these three signal categories. Jenstad, L. M., Bagatto, M. P., Seewald, R. C., Scollie, S.

Table 4. Typical music dynamic markings. 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. Cloudflare Ray ID: 617290cfff662713 A genre-specific analysis revealed that the recorded music samples of all genres generally had smaller dynamic ranges than the speech samples. ,{i:'fig1-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig1.gif',l:'10.1177_2331216516630549-fig1.jpeg',size:'450 KB'}]} The quality ratings were subjected to a repeated-measures analysis of variance (ANOVA) with session (test, retest); condition (linear, semicompressive, compressive); and genre (choir, opera, orchestra, pop, schlager) as within-subjects factors. 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. The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article. The participants conducted listening tests on two separate occasions to compare the linear, semicompressive, and compressive parameterizations. The vocal range of classical performance covers about five octaves, from a low G1 (in scientific pitch notation) to a high G6. Assuming an average of 3 hr per concert, the accumulated amount of live music consumed within a year would be less than 40 hr. window.figureViewer={doi:'10.1177/2331216516630549',path:'/na101/home/literatum/publisher/sage/journals/content/tiab/2016/tiab_20/2331216516630549/20161130',figures:[{i:'table1-2331216516630549',type:'table-wrap',g:[{m:'10.1177_2331216516630549-table1.gif',l:'10.1177_2331216516630549-table1.jpeg',size:'751 KB'}]} mf, standing for mezzo-forte, meaning "moderately loud". Changes in spectral shape across conditions would impose a bias.

Composers specify these dynamics in the notation in their scores in a way that did not happen in earlier music. Perhaps a stupid question but I'm trying to get my head around dynamic range compression of classical music CD's: If JRiver Media player can be trusted most classical tracks seem to have been mastered with a dynamic range of about 15-20 dB. ,{i:'fig6-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig6.gif',l:'10.1177_2331216516630549-fig6.jpeg',size:'306 KB'}]} There are many situations, where a big difference in levels - a high dynamic range - is justified: for instance, in a movie theater, optimized for listening and without any outside noise, or in classical music.

We particularly want to thank Dr. Markus Hofbauer and Dr. Peter Derleth for their valuable support and our fruitful discussions. 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). This number represents the difference between the peak decibel level on a recording and the recording’s average loudness. More subtle degrees of loudness or softness are indicated by: mp, standing for mezzo-piano, meaning "moderately quiet". A Canadian study with a sample of 1,232 participants (Crofford, 2007) yielded an average of 10.5 live concert attendances per year. Group A started with judgments about the sound quality dimension, while Group B started with judgments about the dynamics dimension. The optimal compression strength, however, varied on an individual level. When a composer writes a forte into a part, followed by a piano, the intent is for the music to be quite loud, and then suddenly quite soft. In contrast to other loudness models such as the well-established Cambridge loudness model developed by Moore (2014), DLM supports the loudness calculation of nonstationary signals in hearing-impaired listeners. The stimuli were looped endlessly, and the transitions from the end to the beginning of each loop were not noticeable, as the music segments were selected to preserve musical phrasing. To avoid anomalies at the transitions, the segments were linearly cross-faded with a 50-ms window. I'm just wondering if there's a good reason for albums of orchestral music to be mastered with such large dynamic range when it frequently makes quiet passages quasi inaudible unless the volume is turned up quite a bit, at which point louder passages reach levels that can damage hearing? ,{i:'fig7-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig7.gif',l:'10.1177_2331216516630549-fig7.jpeg',size:'66 KB'}]} ]}. For virtually all electronic dance music, pop, metal and hip-hop made in the 00’s people are used to hearing everything maxed out with no dynamic range. To understand the reason for these perceptual differences, participants were asked after the tests to verbally describe their subjective quality criteria. Streaming services could potentially incorporate information about the dynamic range so that the hearing aids can optimize the compression accordingly. The current study was based on recorded music. The scales used for the ratings ranged from poor to good for sound quality and from low to high for dynamics. To simulate each participant’s individual hearing loss, the air-conduction thresholds, bone-conduction thresholds, and uncomfortable loudness levels at 0.5, 1, 2, and 4 kHz were entered into the model. ,{i:'fig6-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig6.gif',l:'10.1177_2331216516630549-fig6.jpeg',size:'306 KB'}]} The differences between conditions were significant, F(1.4, 42.9) = 4.81, p = .022. Important Notice! Teaching Dynamic Activities. The “Unofficial” Dynamic Range Database uses a sliding scale from 1 to 20 (1 being the worst, 20 being the best) to rank the dynamic quality of each of the recordings they list. 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. Your IP: 50.115.120.237 We ran the repeated-measures ANOVA with a between-subjects factor that divided the participants into two subsets: One subset contained the participants who started with evaluating differences in dynamics (N = 15), and the other subset contained the participants who started with evaluating differences in quality (N = 16). • In either case, the playback media couldn’t handle it. Financial support for this research was provided by ETH Zürich, Phonak AG, and the Natural Sciences and Engineering Research Council of Canada. The mean difference scores are displayed in Figure 7. However I'm looking for the dynamic of the dynamic. There were no interactions between session and condition, F(1.39, 41.6) = 0.130, p = .800; session and genre, F(2.49, 74.5) = 0.728, p = .514; or condition and genre, F(5.5, 164.4) = 1.746, p = .120. Discuss hearing aid selection choices and fine-tuning adjustments that may improve hearing aid sound quality for music. I realize pretty much all concert pieces (classical) are recorded with dynamics in mind. Live music tends to have a larger dynamic range than the recorded and mastered reproduction; however, nowadays, the consumption of live music is far less common than the consumption of recorded music.

The one I've found is Sir Granville Bantock: Hebridean Symphony; A Celtic Symphony; The Witch of Atlas; The Sea Reivers [Royal Philharmonic Orchestra/ Handley] The test stimuli for each participant were generated by recording the music segments with a KEMAR manikin (model 45BB by G.R.A.S.) In each trial, participants had to rate 3 stimuli on a scale from 0 to 100. A reason why the least compressive condition consistently yielded the best sound quality might be that the primary focus in music listening is enjoyment rather than intelligibility (Chasin & Russo, 2004). I restored those entries and have temporarily disabled the delete and edit functions to prevent further damage. The two basic dynamic indications in music are: p or piano, meaning "quiet". ,{i:'table2-2331216516630549',type:'table-wrap',g:[{m:'10.1177_2331216516630549-table2.gif',l:'10.1177_2331216516630549-table2.jpeg',size:'165 KB'}]} Total music consumption, however, has been estimated at 2.5 hr per day (Bersch-Burauel, 2004), adding up to over 900 hr per year.

The idea is that louder = better. While instrument separation, liveliness, clarity, bandwidth, and intelligibility of lyrics were assessed as positive factors, inaudible passages or loudness peaks were mentioned as detrimental for sound quality. Car radios therefore have to operate within a restricted dynamic range. It's the difference and distance between the loudest peak in the track, and the quietest sound. Listeners might be more sensitive to distortion introduced by compression in music than in speech. Dynamic range compression (often shortened to just “compression”) is a process that limits the volume range of a piece of music. ,{i:'fig7-2331216516630549',type:'fig',g:[{m:'10.1177_2331216516630549-fig7.gif',l:'10.1177_2331216516630549-fig7.jpeg',size:'66 KB'}]} The quality of the linearly processed stimuli was judged to be best, followed by the semicompressive and the compressive setting.
