A nice little program analyzing your audio.
Supports WAV, FLAC, AIFF, ALAC, DSF, DFF from 1Bit to 24Bit with sampling rates between 44.1 and 384 kHz and DSD64 / DSD128 (resampled to PCM).


Features:

TPM: True Peak Meter
RMS: (Root Mean Square) 400 ms averaged RMS
CREST: Indicates the amount of dynamic compression

Loudness (according to the standards EBU R128 and ITU-R BS-1770)

M = Momentary = 400 ms
S = Short Term = 3 s
I = Integrated = Averaged over the whole music track
LRA = Loudness Range produced by the music track

Linear Frequency Spectrum: the frequencies in the recording.
Spectrogram: the spectrum over time.

The website and the online manual explains all this measurements and present use cases like checking if a high-resolution recording is truly high-resolution or a upsampled CD.

A DSD64 file.
Typical DSD is the enormous amount of quantization noise starting at 22 kHz.

A 24 bit / 192 kHz file with a lot of high frequency noise.
Notice the blue bands in the spectrogram.
Makes me wonder what the source is.
