Acoustic guitar with USB port, and software for recording https://blog.techtalkradio.com/acoustic-guitar-with-usb-port-and-software-for-recording/?utm_source=rss&utm_medium=rss&utm_campaign=acoustic-guitar-with-usb-port-and-software-for-recording https://blog.techtalkradio.com/acoustic-guitar-with-usb-port-and-software-for-recording/#respond Mon, 30 May 2011 07:35:41 +0000 http://blog.techtalkradio.com/?p=1491 Read More]]> Paring electronics with musical instruments has been going on for a long time.  But this was the first of its kind I’ve seen…

The Jammin Pro USB Acoustic 505 has built-in “toys” and features:  a chromatic tuner with LCD display, a pre-amplifier with a four-band equalizer, XLR out port, and a 1/4-inch jack out.

A 5-foot long USB cord is included.  A 9-volt battery must be inserted into the guitar for it to work with a computer…Windows recognized the guitar in the Recording section of the sound properties as a “Microphone – USB PnP Audio Device”.  I was able to record using Sound Recorder (in Windows)…

Initially, using the tuner, I was unable to correctly tune some of strings:  it indicated that the strings were tuned…but I wanted to check with another source (because it’s been months since I’ve tuned a guitar).  I used http://www.howtotuneaguitar.org to get into the general neighborhood of the tones/octaves.  When doing so, I feared I was tuning the strings much too tight…but after ignoring that feeling I found that once I was in the general area of proper tone, the tuner on the guitar helped to get the strings pitch-perfect.  (I’m just long out of practice…)

A copy of MAGIX Music Maker SE (http://www.magix.com/us/music-maker/) is also included for recording from the guitar.

I think this makes a great gift for someone who is interested in learning how to play the guitar, and those who are interested in creating music.

Jammin Pro has suggested that purchases be made from participating retailers (such as http://www.bhphotovideo.com, http://www.teptronics.com, and http://www.midtownsounds.com).

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

The mCube Slim is a power adapter for laptop computers.  Using AC Input from 100 to 240 volts of alternating current (AC), it can deliver direct current (DC) at:  between 15 to 17 volts (at 4.06 amps), 18 to 21 (at 3.3 amps), and 5 volts at 1 amp for USB devices.

It’s 100x57x18 mm (3.9″x2.2″x0.7″), and only weighs 150 grams (5.2 ounces).  Though it will fit in a pocket, a travel pouch is provided for:  the unit, the AC Input Cable, and the DC Output Cable with it’s assortment of adapter tips for connection to devices.  If one of the tips included with the unit doesn’t work for a device, “…we will arrange for a free compatible tip to be sent to you…”  You can check to see if a particular unit is compatible with the mCube Slim by going to their website and clicking on the “Check compatibility” link.

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

The mMini DC 10 is a power adapter for use in vehicles with 12 volt outputs…

It has two USB ports that deliver 10 watts of power at 2 amps.  (At 69mm x 23mm x 25mm, and weighing only 22 grams) It’s another item that can be put in your pocket to keep your power hungry mobile devices fully charged and ready to use!

Handheld recorder review: iKEY-AUDIO HDR7 https://blog.techtalkradio.com/handheld-recorder-review-ikey-audio-hdr7/?utm_source=rss&utm_medium=rss&utm_campaign=handheld-recorder-review-ikey-audio-hdr7 https://blog.techtalkradio.com/handheld-recorder-review-ikey-audio-hdr7/#comments Mon, 08 Nov 2010 08:36:06 +0000 http://blog.techtalkradio.com/?p=1010 Read More]]> The iKEY-AUDIO HDR7 is a new handheld digital “Portable Field Recorder” for professional-quality recording to SD/SDHC cards, and USB drives…AND IT IS RICH WITH FEATURES!
I expected it to have more weight to it, but it’s very light:  only 0.55 pounds/0.3 kilograms.  It measures 6.22 inches long, 2.87 inches wide, and is 1.46 inches deep (158 x 73 x 37 mm).

At the top are two condenser microphones in an X/Y configuration, a 1/8-inch (3.5mm Jack) stereo line input socket, and a combination 1/8-inch (3.5mm Jack) stereo headphone/line output socket.  A wind screen is included.

On the right-side:
the Standard-A USB 2.0 port for storage drives…
for connection to a computer, a Mini-B 5-pin USB port…
the mic gain switch…
an “OUTPUT LEVEL” control for adjustment of the headphone level…
and a 1/8-inch (3.5mm Jack) stereo microphone input socket.

From the User Manual:  “The HDR7 unit will only interact with one memory device at a time, and the USB drive gets priority over the SD card…when a USB memory stick is connected, only files stored on that device will be viewable.  As well, all recordings will be stored on just the USB drive when it is connected.  When there is no USB drive connected, the HDR7 uses the SD card to read files and store recordings.”

On the left-side:
is an input gain switch with three levels (20, 0, and +10 db)…
the power switch…
and the 5-volt/1 amp “DC INPUT” port for the included AC adaptor.

The SD card slot on the bottom allows for recording onto FAT and FAT32 formatted SD or SDHC cards (64 MB to 32 GB).  The included tripod stand also connects at the bottom…

An SD (or SDHC) card must be insterted, or a USB drive must be connected, before the HDR7 can be powered-on.

Included is:
a USB cable (Standard-A and Mini-B 5-pin plugs)…
four AA batteries…
and a 1 GB SD Card.

Freq Response:      20Hz – 20KHz

Supported file formats:
Waveform Audio Format (WAV)
MPEG-1 Audio Layer 3 (MP3)
Advanced Audio Coding (AAC)
Audio Interchange File Format (AIFF)

The sampling rates (the number of samples per second taken from a signal) available for WAV and AIFF files include 44.1, 48.0, 88.2, and 96.0 kHz.

For WAV and AIFF files, bit depth (how many bits of sound are utilized within a particular sound sample) can be recorded at 16-bit and 24-bit.

And bitrates (how many bits per second are being processed) for MP3 and AAC are 64, 96, 128, 160, 192, 224, 256, and 320 kbps.

Recording levels can be adjusted using an on-screen (volume unit/VU) meter.

Other features:
Automatic Gain Control (AGC) – a mid-range frequency compressor to enhance vocals
Compressor – Condenses the signal so it sounds fuller
Limiter – to ensure a file does not reach too high of a level and become distorted
Noise gate – so audio below a certain threshold does not get recorded

When engaged during recording, auto-track will begin a new file after there is a “prolonged silence”.

At preset increments, during a recording, file timer will begin a new file.

“But wait…there’s more!…”

Guitar and chromatic tuners are built-in…just connect a guitar to the HDR7, and you can stay on key.  (Per the manual:  “The Guitar option is meant for the more novice guitar player, and the Chromatic is for intended for more skilled players.”)

Recordings are stored to /ikey/folder/

For better stereo recordings, I suggest an external stereo microphone be used.

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

UPDATE:

A file to update the HDR7 to version 1.0.37 has been released.

After downloading it from their website, and following the instructions in the User Manual, my unit did not update.

I posted a message on their Facebook page (http://www.facebook.com/topic.php?uid=120247142274&topic=16194), and found others were having the same problem.

To resolve the issue, the file must be renamed (see the discussion in their Facebook account).
