LAME resampling bug?

 

And, changing type of lame_internal_flags::resample_ratio variable from FLOAT to double eliminates these lines.

Added: eliminates these lines ...but only for short samples 
 

LAME resampling bug?

Also changed type of variables that are significant for resampling:

util.h:
Code: [Select]
        double   resample_ratio; /* input_samp_rate/output_samp_rate */
...
        double *blackfilt[2 * BPC + 1];
        double   itime[2];

util.c:
Code: [Select]
inline static double blackman(double x, double fcn, int l)

blackman():
Code: [Select]
    double   bkwn, x2;
    double const wcn = (PI * fcn);

fill_buffer_resample():
Code: [Select]
    double   offset, xvalue;
    double   fcn, intratio;
    sample_t  *inbuf_old;
...
            double   sum = 0.;
...
        double   time0;

NOW works. Don't know whether all these changes were nessessary.
