imho, the only sensible place to do this is the actual audio backend code (s_audio_*.c), since your audio backend might support double floats (e.g. jackd is prepared for that already, though i don't known whether anybody ever used it that way). you don't want to do the calculations in double, then convert to single only to output as double, do you? fgmadr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk4xMXsACgkQkX2Xpv6ydvRedACeLQ+kcKMaXRwz4n6p2Dquje4P 118AoKXn+0TMlRKSO7VPrc9HOZO/Vu88 =X+v+ -----END PGP SIGNATURE----- _______________________________________________ Pd-dev mailing list [email protected] http://lists.puredata.info/listinfo/pd-dev
