Condivido anche qua, la guida che feci qualche mese addietro:


https://www.youtube.com/watch?v=LgtTl-Qr704

spero sia utile per qualcuno...:birra:

Annotazioni:
1. nel video, a livello sequenziale, prima viene caricato il file di calibrazione della scheda audio e poi viene fatto vedere come si effettua tale calibrazione...chiaramente, nel momento in cui si procede alla calibrazione, bisogna prima effettuarla e poi caricarla :)

2. Relativo alla calibrazione dell'SPL, ho scritto:"cliccate su OK e in automatico RoomEQ effettuerà la calibrazione dell'SPL"
In realtà è meglio specificare che RoomEQ non può calibrare in automatico l'SPL...ecco perchè nella fase precedente, viene detto di munirsi di fonometro in modo da regolare i monitor sino a leggere 75dB SPL (o comunque la pressione sonora desiderata).
Fatto questo passaggio FONDAMENTALE e utilizzando la funzione "calibrate", voi direte a RoomEQ quale sarà il riferimento da prendere in considerazione.

Revision History
V5.13 16th August 2015

Reverted to requesting 512M RAM on startup, can be increased by editing roomeqwizard.vmoptions in the installation directory if required
Added optional frequency-dependent windowing of the impulse response, with default settings in the Analysis preferences
Added a psychoacoustic smoothing option
Added an Equivalent Rectangular Bandwidth smoothing option
Improved the Gaussian approximations in the smoothing algorithms
Changed the spectrogram background colour to match other graphs
Added an option to normalise the spectrogram plot to the peak level at each frequency
Added an option to plot the peak energy arrival time curve on the spectrogram
If the peak of an imported impulse response is near (within 1%) of the start or end of the file, rotate the response by half its length. This allows import from packages that put negative time data in the second half of the response
Export measurement as text will export unsmoothed, linear spaced measurements at their native resolution. This produces very large files, for many uses it will be appropriate to apply smoothing to a measurement before exporting it, in which case it will be exported at a multiple of the smoothing octave fraction
Bug fix: When saving miniDSP filter settings on OS X the filename included the path
Bug fix: When starting up with ASIO drivers selected SPL meter calibration status could be forgotten
Bug fix: Cursor frequency was incorrect on room sim graph when the graph extended to 10 Hz
Bug fix: Graph cursor values did not update when the graph scaling changed
Bug fix: Air temperature spinner arrow buttons on Thiele-small parameters dialog did not change temperature
Bug fix: Trace arithmetic merge did not work if measurements being merged were imported responses with magnitude data only

V5.12 29th May 2015

The Measure dialog now appears on top of other windows
The arrow keys can be used to move the graph cursor or (with Shift pressed) the graph itself in pixel increments (click on the graph first)
The x and y keys can be used to zoom in (with Shift pressed) or out horizontally and vertically (click on the graph first)
Bug fix: When starting up with ASIO drivers the SPL meter could show no audio input available under some circumstances
Bug fix: When making a soundcard cal measurement with loopback as timing ref selected the scope Ref Captured trace was from the previous measurement (soundcard calibration measurements do not use the timing reference input)

Added option to use 64-bit FFT processing on RTA when need to resolve below -160 dBFS, e.g. analysing 24-bit digital data paths
Adjusted dual tone f1 level to match the sig gen rms level setting (means clipping occurs if level is set higher than -9 dBFS for 1:1 signals or -6 dBFS for 4:1 signals)
Modified RT60 calculation to better cope with responses that have a large initial decay
Modified RT60 calculation to cope with responses that are truncated before they reach the noise floor

Bug fix: Fixed scaling error on merge B to A when measurements had different SPL calibration offsets
Bug fix: Impedance measurements can sometimes be affected by an inter-channel timing difference, possibly related to running the card at a different rate to the REW rate. If a timing difference of 1 sample or less occurs REW compensates for it, if more than 1 sample a warning is shown.
Bug fix: distortion data was not generated for first measurement after startup
Bug fix: Graph axis selector could disappear when trying to select from dropdown on OS X

Scusate la secchiata di ossigeno liquido sugli zebedei e non abbiatene a male (mi ci metto dentro anche io) , ma al nostro livello sono seghe mentali !
Se nn si sa come agire data una determinata risposta (e l'esperienza di Edi insegna) è inutile , se non a livello propedeutic-accademico tentare una qualsivoglia forma di correzione mirata.
O meglio , curiamo "a prescindere" modali e riflessioni esagerate tramite matematica , buonsenso e BB /limp/abs vari ed eventuali ma non avventuriamoci in imprese che nn siamo in grado di gestire , si rischia di perdere tempo e soldi senza ottenere un vero guadagno significativo (se nn peggio).
Ripeto , "al nostro livello" ovvero quello di chi sta approcciando all'argomento trattamento acustico ma nn necessita ASSOLUTAMENTE di avere un ambiente super-controllato , intendo dire che nn si è dei PRO con clienti a flusso continuo.
D'altro canto se proprio necessita e nn si è in grado operare esistono professionisti in grado di risolvere egregiamente.

Davide , mi permetti di essere sbronzo (con la T però :D ) ?
Hai mai provato a lavorarci nella tua CR ?
Giusto per capire se e quanto i difetti che rilevi sperimentalmente incidano sul lavoro.
No perchè non vorrei che nel tentativo di raggiungere la perfezione ci si dimentichi il vero scopo della situation !

Si ci lavoro, in questo periodo quotidianamente. Il problema che si pone è il solito, fai un export, lo carichi in macchina, in sala prove, nell'impianto in salotto (quello non è proprio fedele ma..) e ti ritrovi le medio-basse pompate a manetta, non penso sia un caso se è l'intervallo 80-100Hz a dare problemi. Sia chiaro, non sto cercando la perfezione ma un escursione di 20dB la sente persino mio cuGGino :D
Ti dirò, per fortuna al momento sto lavorando solo su delle basi per una band, sono arrivato al punto di renderizzare tutti gli strumenti senza gli effetti per lasciarli a parte, un po' per le automazioni, un po' per il presagio che nell'eventualità di prove di un live possa dover ritoccare qualcosa.

Male e molto instabili, qualche centimetro più avanti in un modo, poco più indietro completamente in un altro.. Il vero problema è che inconsciamente durante le equalizzazioni tendo a riempire ciò che la stanza toglie e lavorare così.. Boh.. Certo, non sono un professionista e non pretendo il mondo, ma il trattamento avrei preferito avesse agito in un'altra maniera..

Ti dico la mia che vale come un paio di mutande con l'elastico sfondato.
Io me stesso medesimo avrei (ed ho) preferito delle traps a pannello vibrante in vece dei risonatori.
Tecnolgia piu easy e meno sensibile al diy.
Tralaltro nn vorrei che l'instabilitá che rilevi sia esasperata dai risonatori stessi.
Ripeto , secondo me , meno si sa muoversi più si deve rimanere sul semplice.

Su questo non ci piove, il fatto è che niente risponde come dovrebbe, ogni cosa è sbagliata, tutto lavora al contrario di come dovrebbe.. Cioè fanno il loro lavoro esatto, a me serviva (e mi aspettavo) il lavoro contrario.

Mi danno l'idea pur essendo sistemi passivi di fungere da "sustainer".
Per quello istintivamente propendo per i LMA che sono cmq sistemi che naturalmente tendono a smorzare.

Da quanto ho capito i risonatori di Helmholtz fanno da sustainer solo se li costruisci, male. :D

bene io sarei in procinto di fare la verifica della risposta in frequenza della mia room, quello che ahimè' non riesco a comprendere e' che curvatura bisognerebbe più' o meno ottenere per poter considerare la room accettabile in risposta in frequenza? help jajajaja

le migliori regie del mondo hanno oscillazioni anche di 6 dB lungo lo spettro (+-3) ma non a frequenze adiacenti. L'obiettivo sensato è non avere le montagne russe o un elettrocardiogramma per un spl ragionevole a cui poter lavorare (anche 70 dB C). Piatto come una mazza è impossibile.
