Can anyone recommend any software (ideally Linux, or Win7 at a push) that will give me a real time frequency plot? I’m hoping to be able to hitch my laptop up to the sound head pre amp and get some idea of what is going on... or do I need to go out and buy a RTA because the software/soundcard ones aren’t very good? ------------- Sound is analogue, get over it! |

| i've never tried it but http://sourceforge.net/projects/brp-pacu/ - BRP-PACU might be of some interest... i'll check it out sometime when i have a proper sound card.. |

| I agree with Jonminns - Eaw smaart is the dogs, had some fantastic results with it. You do need a bllody good understanding of the physics of audio to get the best out of it! |

Isn't Smaart very expensive? ------------- Sound is analogue, get over it! |

does smaart allow the import of mic calibration files? i couldn't find any mention in the manual, although i use holm impulse or room eq wizard (REW).

You can create custom weighting curves in smaart so i guess this would be the answer ------------- n^2 modulo -P = number wang |

The free one is only octave resolution. The Allen & Heath Realtime Analyser is also free and does 1/3 octave. |

Have to be very careful with software licensing here! Just had a very quick look at TrueRTA (1 octave) which seems ok but I would need 1/3 octave resolution minimum. I also had a look at the A&H RTA but it doesn’t seem to like Windows 7... unless I’m over looking something? If not I might have to buy TrueRTA or explore the Linux route. ------------- Sound is analogue, get over it! |

TrueRTA sounds ideal for you. the first basic modes of measurements are free which i feel should cover what you trying to do. I not sure if they have it in UK but its quite popular here in states. http://www.trueaudio.com/rta_abt1.htm - Click here for link respeks ------------- Liberate the minds of men, and you will ultimately liberate the bodies of men - Marcus Mosiah Garvey |

According to me EquityRider is an advanced software. This software will Monitor your portfolio for BUY/SELL signals on your criteria. It allows you to create custom indicators, derive indicators based on standard ones, and plot them on charts Real-Time. ------------- http://www.bedsidealarmclock.com/ - travel alarm clock |

not seen much on open-source options in this thread....?
you might like to look at: http://sourceforge.net/projects/brp-pacu/ runs on both Linux and MAC OSX although flagged as a beta development, it works well here on some older PC Hardware with Linux, although users need to know how to compile it. also it's a bit difficult to find as 'Google' searches for it return nothing Mik |

....did see that, Cravings, but you indicated you hadn't tried it
I have this software running using an M-Audio Audiophile 24/96 PCI card on the analog Line in/out's, so it's fair to assume that any other full duplex card/adapter with the same or better spec will also work, so long as it is supported. A minor downside is the need for an additional external Mic Preamp with phantom power. I also would like to try the external unit suggested on the BRP_PACU website, or one of the RME or other 'high-end' ones perhaps? - one day if I can ever afford it Mik |

| i haven't tried it, no. i don't own an external sound card, or a laptop. they're both on my list (i can't afford my list :() though. have you compared results from brp with smaart or any other software? i've never used smaart so will try a few things out whenever i get tooled up... |

I haven't run direct comparisons as you ask, don't have any Window$ loaded PC's here at all, but so far this software package seems to do what I want for the project I have in hand.
Still getting to grips with all of the functions and just beginning to start to compile a 'wish list' for additions/improvements given it's Beta development status. Mik |

| yeah. i don't have any windows either. but i'd consider running a laptop with windows / smaart for a bit just to get a feel for it. i hope to get moving on this soon, would like to start using brp... i get the feeling the developer might like to know other people are using it or intending to. |

sorry - on the hardware requirements, I missed a section in the README file which should interest many:
quote: Why is there no documentation? - Channel 1 is the output of the system we are observing (measured), channel 2 is the input (reference). You also need a decent calibrated omnidrectional microphone (reasonably flat 20Hz-20kHz) and either a USB-Preamp like the 2-channel M-Audio, or a mixer with a 30dB pad or so going into the laptop mic input. No Pad is necessary if you are lucky enough to have a laptop or PC with a line input. The headphone out will have the pink noise. ............one day I'll read the instructions first! Mik |
