A long time ago, around 1963, my uncle gave me an old 5.25 inch 2 track tape recorder. I learnt a lot about tape recording and getting good sound reproduction.

I worked at the English Language Institute at Victoria University of Wellington from 1964 to 1968. This was a part-time position to support my university studies. I used tape recorders to record English lessons for the language laboratory. I learnt to record clear speech.

At home, I recorded many English language samples, from various radio broadcasts, for use in class as listening exercises. I also prepared music tapes and recorded a few live student concerts.

I recorded the Apollo 8 1968 Christmas trip around the Moon. I used shortwave broadcasts from the BBC, VOA and local AM RNZ broadcasts. Like many people of my generation, lots of recordings were made from radio programs.

Zoom F2 Field Recorder

Recently I have updated my recording setup. Instead of a 30.5 kg Akai GX-400D PRO Stereo Tape Recorder and a 3.73 kg Uher 4400 Report - Stereo Tape Recorder I now use a Zoom 32 Bit F2 Field Recorder weighing just 56 grams. It records in mono, which suits me as I have lost hearing in my right ear due to a neuroma. With a single microphone there is little point recording in stereo. An omnidirectional Zoom LMF-2 Lavalier Microphone is provided with the F2.

Currently I use this mainly for live music recording, working with a local band called Black Tartan. At this stage I am still settling on an ideal microphone setup which is unobtrusive, on the stage and near the band. To do a recording I simply turn the Zoom F2 on and press the record button, after a short delay. No volume level adjustments are needed. The recordings are an archive rather than a professionally recorded production. They are, however, very nice to listen to.

Rode VideoMicro Microphone

I have tried a few inexpensive microphones. They all have defects. The best microphone I have found so far is the Rode VideoMicro Microphone.

For music, using the program Audacity, I created a filter curve identical to the published Rode VideoMicro frequency response. Inverting the curve produced a nearly flat frequency response from the microphone. Adjust to taste.

Rycote Lyre Suspension Mount

The Rode VideoMicro Microphone comes with a Rycote Lyre Suspension Mount. This mount is quite wobbly, but only because it is not used properly by many users. This is a typical 2-legged stool problem. The third leg is provided by securing the 2.5 mm microphone cable in the notched ring below. The Internet has many reviews showing the incorrect use of this microphone mount.

At the end of this Video from Rode The correct way to clamp the microphone cable is demonstrated. Note that any physical disturbance of the microphone cable is also isolated.

With a 3 mm cable or larger, use a cable-tie to attach a short length of 2.5 mm cable about 60 mm from the microphone plug - photo (1) at right. Once the 2.5 mm cable part is clamped in the notched ring, the microphone is acoustically isolated and mechanically stable.

Tripod Mount

The Rode microphone and the Zoom are now both mounted on a very basic tripod, as shown below. The tripod has flexible legs and a clip for keeping it in a pocket. With the aid of some tiny O-rings this clip provides a stable mount for the Zoom F2.

I like simplifying designs. The original version was similar to photo (3) at right. The foam-plastic base isolated any sounds from the floor.

I added a cheap ball-mount to support the microphone. The knob to the right of the F2 is not a volume control. It replaces the ball-mount clamp fitting, which broke. Photo (2), at right, shows a microphone cover made from an old medicine container. Long-term it is best to keep microphones dust free.

Simplified Tripod Mount

Recently I purchased a Rode VideoMicro II microphone which has a more compact Rode Helix mount. I removed the tripod ball mount and the complete assembly now fits in my jacket pocket. Microphone tilting can be done by bending the tripod legs. I will test if this microphone is also suitable for my music recording.

My pocket tripod is more than 40 years old. Fuji makes something similar for their Instax cameras.

Rode AI-Micro Compact Audio Interface

The Rode AI-Micro Compact Audio Interface allows a phone or a computer to be used to record sound from up to two microphones. Connectors for all output-to-device options are provided. Microphones can have either TRS or TRRS 3.5 mm phono connectors. There is also a 3.5 mm headphone socket for directly monitoring audio at a convenient volume. The interface can be controlled by software such as Rode Reporter.

I mounted a Rode VideoMicro Microphone on a small tripod. The tripod is placed on a large plastic lid with washers to locate the legs. There is a metal disk under the lid for reinforcement. The tripod is secured to the base with some elastic cord. A foam-plastic base underneath provides acoustic isolation from the floor. Photo (3), at right, shows the complete assembly.

In the background my iPhone is running the two-channel Rode Reporter application.

Zoom H1N Field Recorder

I purchased the Zoom H1N Field Recorder at a greatly reduced price. I assume a new model may replace it soon. This recorder is an update to the Zoom H1 Field Recorder. I like the H1N as it is easy to use and it records quality stereo sound. It can also be used as a USB audio interface.

As a self-contained recorder the Zoom H1N can be mounted on a tripod - photo (4), at right.

If two microphones need to be connected, a splitter cable is required. The two microphones can then be connected as a stereo pair. Two Rode VideoMicro Microphones work well. I also obtained these microphones at a greatly reduced price.

A Rode SC1 3.5 mm TRS Splitter Cable is shown below. Two microphone plugs connect to a recorder plug. The black microphone cable plug-tip is connected to the recorder plug-tip. The red microphone cable plug-tip is connected to the recorder plug-ring. An extension will be required on one arm if a wide microphone separation is required.

Two microphones in an XY configuration and a Zoom h1N recorder are shown in photo (5), at right. The microphone choice assumes lower frequency instruments are on the left and higher frequency instruments are on the right. The setup is rotated 180 degrees to face the music.

Sony ICD-PX470 4GB Digital Voice Recorder

I do not own the Sony ICD-PX470 4GB Digital Voice Recorder with built-in USB Notetaker but it seems to be a very useful and practical device. It is also the least expensive recorder discussed here. There are many convenient features, including variable digital playback speeds with a range from 0.25 to 3 times. The recorder can also be used as a music player using the built-in 4 GB storage.


The Zoom F2 Field Recorder is my current favourite for audio recording. Its simplicity means that, almost always, a good recording is obtained. A good microphone makes that a certainty.

Three options for good audio recording are presented here. Any one of them would be suitable for personal recording purposes. They are not expensive when compared with my old tape recorders.

Lastly, I have described some practical ways of improving low-cost sound recording equipment. I would like to thank Aileen, Hilary and Jason of Black Tartan for allowing me to record their music.
