High Resolution Audio - Audio Analysis

UK This Audio Analysis shows a Crash Cymbal in different resolutions with uncompressed audio codec (WAV):
  ➨ Differences in the frequency spectrum in relation to the sample rate
(in kHz / rows 2, 3, 9 and 10)
  ➨ Differences in the noise floor and the quantization noise in relation with the amplitude resolution
(in bit / row 6-8 and 17-19)
  ➨ Phase and frequency shifts above 10 kHz in case of downsampling to 44.1 kHz
(rows 4, 5 and 10-16)
  ➨
Quantization and interpolation errors after sample rate conversion from the original 192 kHz source (rows 17-19)

UK Please note: One time the FFT filtering has been done after sample rate conversion (row 10 and 12, downloads), one time the sample rate conversion after the FFT filtering (row 11, 14 and 15). First proceeding results especially for the stereo channel at 44.1 kHz more in a phase shift in direction of mono, compared with the original source in 192 kHz, but doesn't make a significant difference in the phase offset between the attacks in the same sample rate, measured at the left reference channel: ~ 295 ns at 44.1 kHz and ~ 292 ns at 96 kHz in both cases (row 10 and 11).

The results have been normalized to 0 dBFS before phase analysis, hence the levels e.g. in row 12 and 14 have been amplified by + 15 dB (compared with the original level in row 19).

 

DE Bitte beachten Sie: Einmal wurde die FFT Filterung nach der Abtastratenkonvertierung durchgeführt (Zeilen 10 und 12, Downloads), einmal die Abtastratenkonvertierung nach der FFT-Filterung (Zeilen 11, 14 und 15). Ersterer Vorgang zieht insbesondere für den Stereokanal in 44,1 kHz eine höhere Phasenverschiebung in Richtung Mono nach sich, verglichen mit der Originalquelle in 192 kHz, bringt jedoch keinen nennenswerten Unterschied im Phasenversatz der Attacks in gleicher Abtastrate, gemessen am linken Referenzkanal: Jeweils ~ 295 ns bei 44.1 kHz und ~ 292 ns bei 96 kHz (Zeilen 10 und 11).

Die Ergebnisse wurden vor der Phasenanalyse auf 0 dBFS normalisiert, von daher die Pegel beispielsweise in Zeile 12 und 14 um + 15 dB angehoben wurden (im Vergleich zum Originalpegel in Zeile 19).

UK Please note, that High Resolution Audio requires a high quality digital/analogue conversion. Onboard soundcards are not capable to play files with 32 bit dynamical resolution, which get down converted during playback. Please take care, that your system is set to 192 kHz.

DE Bitte beachten Sie, daß High Resolution Audio eine hochwertige Digital/Analogwandlung voraussetzt. Onboard Soundkarten sind nicht in der Lage, Dateien mit 32 bit dynamischer Auflösung wiederzugeben, welche dann während der Wiedergabe herunter konvertiert werden. Bitte stellen Sie sicher, daß Ihr System auf 192 kHz eingestellt ist.
