Zimmerman: Judge rejects voice experts testimony.

I don't recall, were those recordings made from a wired or cell phone? If cell,
compression is used which can cause significant changes in the audio. A regular
digital phone channel uses a G.711 CODEC at 64 Kb/s. A cell phone GSM CODEC
compresses that to about 13 Kb/s or little more than 1/5 the G.711 bandwidth.

8000 samples per second 8 bit 300 to 3400hz hardly hi fi, I frequently get
people mixed up on the phone if I have not heard their voice for a while. GSM is
much worse.
Maybe he thought that concatenating the 8 bit sample string and the copy would
make a 16 bit sample, there's a thought maybe he interleaved the samples MSB,
LSB viola 16 bits.

... we know "experts" can be had by anyone for anything. All you really have to do is be able to pay the $500 per hour.

Now... to get real experts - that's not so easy and has less to do with the difficulties of pay.

IMHO this is improper behavior from the prosecutor
Authored by: Anonymous on Monday, June 24 2013 @ 07:34 PM EDT
In our adversarial system the job of the defense lawyer is to do everything
possible within the law to defend their client. The job of the prosecutor is
not merely to get a conviction, but rather to find the truth. In my opinion
prosecutors should not attempt to mislead the jury in order to get a
conviction.

I don't think any reasonable person could have seriously considered the
'evidence' presented by the two 'experts' for the prosecution. The real experts
in the field testified that what the prosecution presented was absurd ... one
even laughed out loud. I find the fact that the prosecution tried to get this
'evidence' admitted to be disturbing.
