Thanks Josh - VocalSlice can function without a GPU so that wont be an issue thankfully.
That is an older CPU - having taken a look into it, it seems that the library i'm using for transcription is compiling with certain features that CPU does not support, but I'm keen to get you up and running, so I'm currently implementing a solution that should unblock your work. Keep an eye out for 0.1.11, i'll try post it up in the next 24 hours, if you could give that a try when it releases.
Josh - having spent some time on benchmarking this, without going too much into the technical side of it, changing the binary to support these older CPUs would require a change which would negatively impact the performance for all users utilising CPU as their chosen device. I was looking into having a separate build to support older CPUs, but I personally just wasn't happy with the performance in testing on a much faster CPU than the i3-2100, so I think for you as my customer, the performance/experience on your current hardware would be sub-optimal.
Typically when trying to transcribe a very short recording, it should take a couple of seconds, but when compiling for older CPU support, it was taking a noticeably longer time.
I will update the minimum specs for Intel to the Haswell generation (2013). I'm very sorry for the inconvenience caused.
