4003/5 sound clip

[cassius987]

Just thought I'd share this clip of my Paul W.-converted 4003/5 to dissuade anyone thinking 33.25'' can't handle low B... Warning: it's a pretty big file, see my p.s. comment below.

p.s.: For some reason the low B really hates to be bit rate compressed (it starts to clip as if it were saturating its input if I use *any* bit rate compression). Anyone know why? I want to get better at recording it without using huge chunks of data in the future...

Sounds fantastic!

Need to know all gear involved, and all settings. Was it recorded at 24-bit/96kHz?

Nice, simple ostinato, add some horns and percussion and you'll have quite the hit, there, Joshua.

Bass -> Apogee Jam -> GarageBand (no effects, just using it for DAW) (24-bit depth, I think 96 kHz as well but definitely higher than 44.1 kHz; the dialogue is not clear about the exact sampling rate at this setting) -> Exported to .AIF for the clip you heard. When I did AAC (Apple's compression format) I got some weird fuzz on the low B part of the time (usually the neck pickup and both pickups but not the bridge pickup).

Fishing for a producer's credit I see... Oh what the heck! You got it.

Also, what is the bitrate of the finished AIF?

Apple's instructions only tell you the recorded and exported bit depth, which in my case is 24/24.

Uncompressed, and the first AAC compression option is 320 kbps so I'm guessing > or = to that value.

It's possible it's a sample rate mismatch but I don't really know. I'm hearing it on other strings beside your B. Does this happen with other instruments?

For several months I thought my old Fender Cyber Twin amp (which I now know outputs 16/44.1 via S/PDIF) was dying when all my recordings had a similar and very noticeable buzz (guitar, not bass, of course). Then I realized I was recording at 24/96, and ProTools didn't like the 16/44.1 it was being fed. Once I realized what was happening, I started setting up a separate session for direct digital guitar tracks to record at 16/44.1, along to bounced tracks of whatever rhythm tracks I'd already completed, and importing the new 16/44.1 audio into my original 24/96 sessions.

I have not been using the Jam to do very many recordings to date so I really don't know. I'm only hearing it occasionally on the B, but I did notice if I have the volume turned down it gets worse(?). Full volume, it sounds really good to my ears, especially this uncompressed version. Maybe the waveform itself is hard for speakers to handle at low volume? I'm not sure. In GarageBand it sounds crystal clear and that's why I used AIF.

The Apogee Jam spec is "44.1/48 kHz, 24-bit analog-to-digital conversion". So bit depth is okay, but I have no idea how to adjust the rate in GB. I can take a screen shot to show you what I mean: GB doesn't display sampling rate info in the recording quality drop box, just depth.

This mp3 version is 44.1 kHz and, since my settings for recording are "best" should have exported at 24-bit depth. (It's also 318 kbps VBR if that matters at all.) Of course I don't know if soundcloud might be tweaking it as well. It sounds good through my earbuds but not as nice as the AIF file.

[jdogric12]

Oh, so you were not hearing the B buzz in the AIF? Just in the mp3? Hmm... I am hearing it in both so we may be zeroing in on two different things. I'm stumped!

What I'm hearing is the same frequency on all 5 notes, so maybe it's a screw rattling or something?

[cassius987]

I'm not hearing the monotone on my end. Can anyone else weigh in?

The switch is kind of tight right now so maybe there's a resonance from it.

Yeah my band tunes down to Bb and I'm just using standard 105-45 strings on a regular 4003. The low Bb sounds fine to me .
