Dealing with low quality recordings?

post #1 of 9
Thread Starter 

My current set up is a pair of Beyerdynamic DT-880s and a FiiO E7/E9 combo, which I love.  However, I am currently doing some work as a scopist for my court reporter friend, which results in me dealing with low quality recordings. 32kbps, lots of static, muddled words, etc. 

 

Perchance does anyone have any ideas on what I could do to make it more listenable?  

 

 

Thank you.

If you could please list how you listen to your low quality court recordings.

 

Example:

 

Court recording device ( insert name here ) --> RCA out to FiiO E7/E9 --> Headphone out--> Headphones

 

The reason for this is to allow us to determine if there is a possibility that the gear is adding noise to the setup.

I am sent a .zip file that has the .wav audio file in it, it is then loaded into a piece of scopist software -- Case CATalyst -- where I listen to it.  

 

It goes Computer > 32 kbps .wav file > Case CATalyst > USB from E7/E9 > Headphones. 

 

^ At least I'm pretty sure that is how it works, heh.

 

 

Thank you for your reply.

So it seems that the problem is your headphones are too good. tongue_smile.gif Maybe consider something that will get the sound farther from your ear such as Koss clip ons.

There's not much you can do with something that low quality. Can't they record in slightly higher quality? Even 64kbps would do.

Since you are dealing with court-room proceedings I would guess vocal conversations, and picking them apart for detail is your primary focus.  The Sony MDRV6/7506 is an industry standard in both TV and radio production and post production monitoring.  The 2-3 models I owned were all very forward and aggressive in the midrange-upper midrange tones, pushing those frequency bands forward in the mix.  I could see why this model is so popular for this application.   Its also closed back and semi-isolating.  The DT880, despite being a very detail revealing headphone, would not be my first choice for this application.

 

[EDIT]  Why are you recording at 32k?  Is there any way to increase resolution at the source?

If you can play the recordings back on a computer, an equalizer might be of some use. You'd have to play around with it, but you could lower the higher frequencies to get rid of some hiss for example.

128 is the lowest you can go before you run into the above problems

The primary issue here seems that the files are poor quality to begin with and without a bunch of filtering and EQ that is really outside the scope of any basic playback program the sound should be terrible.  That at least tells you that your hearing and gear are capable of detecting crap source music / files.
