Dataset: "Increasing loudness in audio signals: a perceptually motivated approach to preserve audio quality"

<p>This archive contains the audio files that were used to test the algorithms presented in the paper entitled: &quot;Increasing loudness in audio signals: a perceptually motivated approach to preserve audio quality&quot;.</p> <p>Listening is to the samples is interesting, however, as the samples are quite short, the listening experience might strongly differ depending on the software and hardware used. We recommend to also look at the waveforms (using Audacity or others) and spectrum to see how the algorithm perform masking in order to increase the headroom of the samples.</p> <p>&nbsp;</p> <p>The archive is composed as follow:</p> <p>In the folder &quot;Original&quot; are the original kick drums used numbered from 1 to 16.</p> <p>The folder &quot;perceptual_alt&quot; contains the samples modified according to Eq(3). Each subfolder number corresponds to the number of the original sample used. The naming is &quot;x_a_c&quot;+lambda+&quot;.wav&quot;. Lambda ranges from 0 to 0.95.</p> <p>The folder &quot;perceptual&quot; contains the samples modified according to Eq(2). The naming is &quot;x_pc_c&quot;+c+&quot;.wav&quot;. c ranges from 0 to 40.</p> <p>The folder &quot;compressor&quot;, &quot;hardclip&quot;, &quot;softclip&quot; contains samples modified according to, respectively, the compressor, hardclipper and softclipper detailled in the paper. The naming is &quot;x_&quot;+{&quot;c_c&quot;,&quot;hc_c&quot;,&quot;sc_c&quot;}+c+&quot;.wav&quot;, where in this case c ranges from 0 to 40 and correspond to the threshold needed to get the same peak value as the perceptual algorithm (2) for a given perceptual constant c.</p> <p>&nbsp;</p> <p>The samples are taken from https:/ /www.musicradar.com/news/drums/1000-free-drum-samples, the names of each individual sample is:</p> <p>1: CYCdh_AcouKick-19.wav</p> <p>2: CyCdh_K3Snr-10.wav</p> <p>3: CyCdh_K3Tom-05.wav</p> <p>4: CYCdh_K1close_Flam-05.wav</p> <p>5: CYCdh_K1close_Kick-08.wav</p> <p>6: CYCdh_K1close_Rim-07.wav</p> <p>7: CYCdh_K1close_SdSt-07.wav</p> <p>8: CYCdh_K1close_SnrOff-08.wav</p> <p>9: CYCdh_K4-Kick05.wav</p> <p>10: CYCdh_K5-Kick93.wav</p> <p>11: CYCdh_KesKick-08.wav</p> <p>12: CYCdh_LooseKick-08.wav</p> <p>13: CYCdh_VinylK3-Kick01.wav</p> <p>14: CYCdh_VinylK3-Kick02.wav</p> <p>15: CYCdh_VinylK3-Snr02.wav</p> <p>16: CYCdh_VinylK4-Tom03.wav</p>
