DO NOT READ BELOW. gimme a few weeks to complete this.
The Sony PCM-F1 is a 96 kHz/24-bit portable digital recorder that runs on two AA cells, USB power or the included 3VDC AC adapter.
The pocketable Sony PCM-F1's technical performance and build quality are significantly better than the more expensive Zoom H4n and the dinky Tascam DR-08. Unlike anyone else making portable recorders today, Sony has been making $50,000 professional digital audio recorders since the 1970s, and this experience shows.
The PCM-F1 records as .WAV or as .MP3 files from its own stereo microphones, line or mic inputs. It has a rotary ganged stereo recording level control on the side. It plays many other kinds of files, including AAC and WMA.
This recorder works for for anything, especially audio for DSLR or other video. You put this recorder up at your subject and let it run, then use software like Plural Eyes to sync the audio to video later. You shoot from where you need to shoot, and the audio is recorded clear and up-close in either direct-to-MP3 or up to glorious 96kHz/24-bit digital stereo separately from your DSLR without any big mics on-camera, or even any wires.
It works great and is super-easy to figure out and immediately record broadcast-quality files. When the REC light is blinking, you're ready, and when REC is solid, you're rolling. Want to make a great downloadable file? Just set it to 128 kbps MP3, record, and upload. Done.

Sound quality depends far more on your ability as a recording engineer than on this recorder. Placement is everything. Recording engineers spend careers learning better and better ways to place microphones.
That said, this recorder is quite transparent; it works very well: it's clean, noise-free and wideband. It's technical performance is far better than the cheap Tascam DR-08 and also much better than the bigger and more expensive Zoom H4n.
Bloodline is important. Sony invented the portable digital audio recorder in 1981 (the Sony PCM-F1), and knows what they are doing. These 30 years of experience are in this little recorder, something no one else in this field has.
The mics and complete recorder sound quite nice. I can't hear anything missing or colored. The true (spaced-mic) stereo is much more spacious than the one-dimensional X-Y only sound of the Zoom H4n, and the PCM-F1 doesn't suffer from the slight upper midrange boost of the H4n.
Listen to these sample recordings:
Reading to the class from 2 meters: 6MB, 6-minutes at 128 kbps MP3 Stereo, AUTO level control.
In AUTO level control, the levels don't get as loud as with the Tascam DR-08 in its AUTO level control.
Much better than the Tascam DR-08, in AUTO level control, I can't get the PCM-F1 to distort if I yell into it.

The PCM-F1 is easy to use. It only takes a moment to set it up for your first recording, after which, you're set. I found no need for the Sony PCM-F1 users manual.
It takes only a few seconds to turn on, never 30 seconds like the Zoom H4n.
The PLAY, PAUSE and REC buttons are lit from behind. A menu option lets you turn these off.
The little -12dB and OVER LEDs are a great idea, except that they are too dim to see except at night.
For dates, the year 2011 shows only as "11y"
This little recorder feels much nicer nice all around than expected; it's a much higher quality product in every way than the more expensive Zoom H4n.
When recording, an annoyance is that the peak level "Margin" display keeps resetting, instead of holding at the maximum for each take.
There is no confidence head; you don't really know that your file will play back until you're done.There are no power-on or power-off thumps.
It's nicer than I expected. The face feels like metal, and the rear battery door is hinged so it doesn't fall off. The bottom has nice rubber feet so it sits nicely on glass tables.
When plugged into a computer, it pops right up as a drive labeled "PCMRECORDER." Easy!
Files are labeled as YYMMDD_##.MP3.
## resets each day to 01.
The output levels are only 1.5 dB more than an iPod touch, so whatever you get out of an iPod is what you'll get out of the PCM-F1's headphone jack.
This means its more than enough for use with the Ultrasone Edition 8, but not quite what you'd want for use with a 600 Ω Beyer DT880. The DT880s sound great with the PCM-F1, just that they may not go as loud as you prefer at full gain.
When playing AAC files copied from iTunes, it reads the titles and artists.
The Sony PCM-F1 measures much, much better than the Zoom H4n or Tascam DR-08. Sony has been making professional $50,000 audio recorders since the 1970s and has learned a trick or two. Sony also makes its own audio chips, so its supremacy here was expected. This little recorder performs as it should, even though a 1990s DAT recorder is still better, while the Zoom H4n and Tascam DR-08 look pretty bad in the lab.
All measurements here are as powered by two Sanyo AA Eneloop. The advantage of this is complete isolation as compared to using USB or an AC adapter.
I used a $50,000 Rohde & Schwarz UPL laboratory audio analyzer to perform these measurements.
OVER lights a little before 0 dBFS.
* Mic preamp clips at 980 mV, at gain = 1 = 0 dBFS.
Oddly, the relative attenuation of what sounds like a traditional stereo pot varies with the selected input.
As a traditional stereo pot, channel tracking will vary (balance will vary with level).
Input Level Control Channel Tracking (LINE Input)
Sony PCM-F1 Record level control channel imbalance (R versus L). (R&S UPL.)
This shows us that the balance shifts a tiny amount to the left at lower level settings, nothing over which to lose sleep. By using a real potentiometer instead of digital control we get real-time infinitely precise level control instead of fixed steps controlled by buttons.
set to Headphones (default):
At 0 dBFS, playback level starts to clip at level 29 and level 30, making level 28 the maximum to use without distortion.
If the menu is used to set the output to LINE instead of Headphone, all it really does is fix the gain.
Set to Line Out:
Playback Level Control Channel Tracking
The output level control is a 31-step digital attenuator which tracks very well as expected:

Output Source Impedance
Set to line or headphones, the analog output source impedance measures 0.72 Ω (720 milliohms) at 1 kHz.
44.1 kHz/16-bit WAV:
Sony PCM-F1 Frequency Response, Line input 44.1 kHz/16-bit. (R&S UPL.)
48 kHz/16-bit WAV:
Sony PCM-F1 Frequency Response, Line input 48 kHz/16-bit. (R&S UPL.)
96 kHz/16-bit WAV:
Sony PCM-F1 Frequency Response, Line input 96 kHz/16-bit. (R&S UPL.)
As expected, the high frequency extension varies with sample rate.
The low-cut filter is extreme, 24 dB/octave at 200 Hz! It will remove all low frequencies, not just rumble and the proximity effect.
Sony PCM-F1 Low-Frequency Filter Response, Line inputs. (R&S UPL.)
THD versus level, line in to headphones out
Sony PCM-F1 THD versus level, 44.1 kHz/16-bit. (R&S UPL.)
Sony PCM-F1 THD versus level, 96 kHz/24-bit. (roll mouse-over to compare to 44.1/16.)
These were measured with 2V RMS LINE input, gain just below 4, output at 30 (max), 1.2 V RMS at 0 dBFS. The input level was varied from 2 mV to 2 V RMS for this test.
Idle Output Noise
A-weighted with 200kΩ load while idle (neither playing nor recording):
1 V at 1 kHz, input gain just above 6, output at maximum (1.2 VRMS), measured analog input to analog output:
89.0 dB (A-weighted) at 96/24 bits WAV.
89.0 dB (A-weighted) at 44.1/24 bits WAV.
91.6 dB (A-weighted) at 44.1/16 bits WAV.
89.0 dB (A-weighted) at MP3/128kbps.
91.6 dB down from 1 V is 26.3 µV (-91.6 dBV) EIN (equivalent input noise).
50 mV at 1 kHz, input gain at 5, output level set to at 28 (1.2 VRMS), measured analog input to analog output:
89.6 dB (A-weighted) at 96/24 bits WAV.
89.5 dB (A-weighted) at 44.1/24 bits WAV.
89.2 dB (A-weighted) at 44.1/16 bits WAV.
89.2 dB (A-weighted) at MP3/128kbps.
89.2 dB down from 50 mV is 1.73 µV (-115 dBV) EIN (equivalent input noise).

The Sony PCM-F1 recorder works for for anything, especially for audio for DSLR or other video. You put this recorder up at your subject and let it run, then use software like Plural Eyes to sync the audio to video later. You shoot from where you need to shoot, while the audio is recorded clear and up-close in either direct-to-MP3 or up to glorious 96kHz/24-bit digital stereo, separately from your DSLR without any big mics on-camera, or even any wires.
You can't just plop it down and go. Recording engineering is an art: microphone placement is everything to recorded sound.
The Auto Level control works great for voice, interviews and presentations. I can't hear it pumping.
I'd use MP3/128k if you want to broadcast the files directly as-is on the internet. The MP3/64kbps setting is for voice note-taking, not for music. The 320kbps MP3 setting is for slightly cleaner MP3 files with double the file size of 128kbps.
If you're going to edit before distribution, I'd use the PCM settings. I'd use 16-bit instead of the 24-bit settings because the 24-bit settings offer no additional audible or measurable quality increase, but waste 50% more file space for bigger files with less recording time. In other words, recording at 24-bits just records 16 bits of audio with 8 extra bits of noise. 16-bits are more than enough to handle the analog circuits of this $300 recorder. To make full use of 24-bits requires much higher-end microphones, preamps and ADCs than in this recorder.
Choose 48 kHz (ksps) for video, TV and film, and 44.1 kHz (ksps) for CD release.
If you want to swap cards while recording, see "Cross-Memory Recording" on page 39 of the Sony PCM-F1 users manual.
The low-cut filter is severe. Avoid using it.
To connect to a computer, just plug it in. Even if the power is off, it will wake up and connect.
After disconnecting from USB, the power stays on, so remember to turn it off.
With a micro SD card, the card and the internal 4 GB memory come up as two drives on your computer.
If you want to see the level meters in playback, you may activate them in a menu.
The clock will need to be reset if the PCM-F1 goes for more than 3 minutes without batteries.
I prefer to set the LCD light to stay on longer than its default, an easy change in the menus.
The Sony PCM-F1 is my favorite portable stereo recorder. It offers excellent technical, sound, ergonomic and audio quality in a small, well-built and inexpensive package.
