@Mwyann
Is this a Breakaway Audio Enhancer 1.44 problem? If so, I’ll move it over there. Please provide some additional information. I assume that you are trying to install BAE 1.44 on an XP PC?On the point of this forum layout, I am not the webmaster, but I have brought it to their attention.
@timmywa I have a response which explains why the sample rate “optimised” at 44.1 kHz
From Leif,
“Codecs tend to have more artifacts at 48 than at 44.1, but once the bit rate is high enough, it becomes a non-issue.
For AAC-LC i set that cutoff point at 160kbps. Anything over that, I pass through the audio engine sample rate to the encoder without conversion, meaning 48 kHz in = 48 kHz out.The sample rate converter in BreakawayOne is very, very good — miles ahead of what you find under the hood in Windows. Frequency-sweep artifacts are like 90dB down in the FFT analyzer. So, in short, I wouldn’t worry about it. ”
Is there any way you could up the bit rate past 160 kbps? Alternatively, just select 48 from the selections, rather than leave it at “Optimised”, which will actually down-convert.
Yes, I see your point. I’ll ask the question and get back to you.
My guess is that 48K is probably only possible/allowed at the higher bitrates, so 44.1K is the best you can get i.e. the “Optimum” sample rate. Wiki tells me that AAC can handle sample rates to 96kHz, so I need to research further.

Are you using HE-AAC or AAC? HE-AAC is optimised for low bitrates (up to 160 kbps), so I’m not even sure that 48 kHz is relevant.
If you are using AAC, why not just select 48 kHz from the drop-down box?
A configuration dump is typically used if you need to send information to CEA in response to a bug, or to apply for a licence.
There is also an option to save your entire configuration and setup to a zipped file. this can be imported to set up a fresh install rather than having to go through every setting manually.
To help explain the rather unusual syntax of the command line, I have snipped an image from the video, so that you can see it graphically.

Yes, I copied and pasted all requests into a spreadsheet and now the development team are prioritising them all.
I have included that as it was requested by another member.
Watch this space, as I know that there has been some recent movement in the development arena.
No hints, no timelines.
FM multipath causes signal interference due to the receiver receiving the signal from multiple paths.
It’s not possible to completely fix it in software, but what exacerbates the problem is stereo separation, due to it increasing the bandwidth of the FM carrier, and we can control that in software.
The Multipath Mitigation control will reduce stereo separation of only frequencies with extreme stereo separation, with very high resolution (something like 1000 frequency bands), meaning an almost imperceptible, usually completely imperceptible reduction in overall stereo width, while tightly controlling the final RF bandwidth and reducing the risk of multipath-induced distortion. It doesn’t eliminate it though, we can only do so much, but it’s probably a worthwhile setting to keep on for most stations.
Low, Medium, High simply adjusts the aggressiveness with which it is applied.
Does it affect the audio quality? Almost imperceptibly in areas where signal strength is good, but definitely provides an improvement in areas where the signal may arrive at the receiver via multiple paths.
