    calculate the offsets from the phase differently, this happens
    to reduce the register pressure in the main loop, which in turns
    allows the compiler to generate much better code (doesn't need

    change how we store the FIR coefficients

    The coefficient table is now transposed and shows
    much better its polyphase nature: we now have a FIR
    per line, each line corresponding to a phase.

    This doesn't change at all the results produced by
    the filter, but allows us to make slightly better
    use of the data cache and improves performance a bit
    (although not as much as I thought it would).

    The main benefit is that it is the first step
    before we can make much larger optimizations
    (like using NEON).

    new coefficients for the vhq resampler

    previous coefficients were provided by a 3rd party and didn't have a
    way to re-generate them. we're now using the 'fir' utility.

    the performance of the filter is virtually identical, except for
    the down-sampling case which seems slightly better now:
       It looks like both the previous and new coefficients are generating
    some sort of clipping for full-scale signals in the down-sampling case
    (although the new ones seem better), the reason for that is
    unknown (see bug: 7453062)

    Also updated the HQ coefficients for the down-samplers, previous ones
    were a little bit too conservative -- the new ones push the cut-off
    frequency up by about 1 KHz.

    the impulse response of a low-pass is 2*f*sinc(2*pi*f*k), we were
    missing the 2*f scale factor. This explains why we were seeing
    clipping and had to manually scale the filter down.

    up-sample coefficient were generated with a cut-off frequency of 24KHz

    also increased the attenuation to 1.3 dB on both up and down

    reenable the cubic resampler

    cubic resampler was disabled because it hadn't been qualified,
    however after I did some tests, it does improve significantly
    the sound quality over the order-1 resampler, even if it is
    still quite bad.

    also HIGH_QUALITY resampler was partially disabled, it's now
    fully enabled. It's a big improvement over the cubic resampler
    in terms of aliasing noise (it's not as good in the pass-band).

    improve SINC resampler coefficients

    - we increase the interpolation precision from 4 to 7 bits
    this doesn't increase CPU power required, it only increases the
    size of the filter table but significantly reduces the noise
    introduced by the quantization of the impulse response.

    - the parameters of the filter are set such that aliasing is
    rejected at 80 dB below 20 KHz. Because we don't use a lot of
    coefficient (to save compute power), there are quite a bit of
    attenuation in the pass-band: starting at 9KHz for the
    down-sampler (48 to 44.1), and starting at 13 KHz for the
    up-sampler (44.1 to 48) -- the transition band is about 15 KHz.

    - added debug option
    - added an option to generate a polyphase filter coefficients
    - added an attenuation option in dBFS
    - added a lot of comments and references
    - fixed kaiser window parameter

    also the default should generate a filter with 80 dB rejection
    (of the 24 KHz aliasing) above 20 KHz and a 15 KHz transition
    band around ~20 KHz (for 48 KHz sampling rate).
    It's not very good but corresponds to the current code.
