No Sound with ION USB TT

[mauibill9]

I am running 1.3.6 on Vista Home which I downloaded from the disc that came with my ION TTUSB10 turn table. I am trying to convert 78 rpm's to my computer to burn to DVD. I hear faint sound as I play the record at 45rpm on the turn table but nothing thru the speakers. After finishing the conversion and changing it back to 78 and saving it as per instrutions I have no sound from the saved file. I have gone over the installation instructions several times and have read a lot of info on this site but have found no answer. thanks in advace for you help. Bill PS I am having no problem using the EZ Vinyl converting 45's or 33 1/3's. Sound, evrything works fine.

When you plug in a USB device like this your computer hands over control of all sound services to the USB device - both input and output. Since your USB TT doesn't have a set of speakers, you then don't get any sound from the computer (not even the normal computer sounds).

All you need to do is to get your O/S and Audacity to retarget the sound output onto your computer's on-board soundcard. In Windows use Control Panel > Sounds and Audio Devices > Audio > Sound Playback (I don't know the MAC equivalent) - in Audacity use Edit > Preferences > Audio I/O > Playback Device - you may need to close and restart Audacity for the change to take effect.

====================

BTW be aware that your ION will be applying RIAA equalization to your signal. While this is the correcct equalization for vinyl recordings it is not the correct one for 78s. Before vinyl recordings each manufacturer og 78s applied their own equalization curves (several of them are programmed already into Audacity (see Effect > Equalization. But note that before applying the 78 equalization you will need to first remove the vinyl RIAA equalization to get an "un-modified" signal. There are plans to introduce such a feature in later versions of Audacity - but for now you have to do that yourself.

Fortunately for you this was all discussed at siome lenght in a thread started by BillW - and he also created code for the necessary equalization profile - see this thread: http://forum.audacityteam.org/viewtopic ... 28&t=14547.

You should also be making corrections for the fact that you are not recording at 78rpm and thus the EQ curve will be incorrectly applied. You may want to look at Brian Davies' recently recently released Equalization software which can be downloaded for free: See: http://www.clickrepair.net/software_dow ... lizer.html

======================

You may also find great benefit from Brian's other software - not free, but well worth the modest price IMHO.

BillW and I both use Brian's ClickRepair to clean up our recordings - and for your 78s you should find the DeNoise s/w useful - see http://www.clickrepair.net/software_download/

See my review of ClickRepair in this thread: http://forum.audacityteam.org/viewtopic.php?f=28&t=1994

Finally, are you sure that you are using 1.3.6? ION normally bundle the latest "stable" version which is 1.2.6 - 1.3.x is Beta software

If you are on 1.3.6 you should download the latest version - and if you are using 1.2 you will still benefit from using the latest 1.3

The Beta releases are pretty stable now and provide many extra useful functions and fixes for bugs that exist in 1.2. You can download the Beta from here: http://audacityteam.org/download/

But also see this thread, as there is a known bug in 1.3.10 which will affect you - the following thread discusses this and tells you how to get the very latest Beta: http://forum.audacityteam.org/viewtopic ... 16&t=20748

Another thought ....

And if you don't use a special stylus designed for 78s then you are extremely likely to not only get very poor sound from the bottom of the groove - but you are also likely to damage the stylus that was designed for the smaller grooves pressed in vinyl 45s and 33s as it bumps and grinds along the bottom of the 78 track.

IIRC ION can supply a stylus suitable for 78s
