What is the sample rate of voice memos?

I often record lectures via Evernote audio notes on my iTouch. I want to convert those audio files to text. A piece of software named, MacSpeech Scribe has caught my eye. A review states, "a minimum sampling rate of 11.025khz" is needed for the conversion.
Does anyone know the sampling rate of an iTouch audio note?
Thanks in advance.

ok i've figured out the physics of this question.
The Cache Read data rate is always larger than the Cache Write data rate, because the computer would have to be rendering to Cache faster than realtime for the Write rate to be higher, which would make it unnecessary to render to cache in the 1st place. So I'm really only worried about the Cache read data rate. Does adobe have a paper that tells us what the data rate is for different sequences.
my 3 common workflows are
canon h.264 1080 24p
AVChd 1080 24p from my GH2 with a 44mb
and
r3d 5k epic footage 24p - (this is painful to edit )
anyone know where this info is?

HT5848 What is the sampling rate and codec for iTunes Radio. Is it lossless encoded?

What is the sample rate and codec for iTunes Radio? Is it lossless encoded?

I have to agree with you. There are several forum discussions on bit rate being as high as 256 kbps but I don't see how it could be more than 96 kbps based on the poor sound quality I'm hearing. I'm comparing it to an internet radio station that is 128 kbps and sounds much better.
Am I missing something?

Sampling Rate- How do I check and adjust the sampling rate on my Laptop?

For the purposes of matching the sampling rates on my laptop to my usb microphone, (recording in garageband) how do I find out what the sampling rates are on my 2009 macbook? Many thanks!

IPhone: AudioQueue - is it possible to change the sample rate?

I've been playing around with the AudioQueue stuff for a few days and it's all working fine.
I was trying to build a low-latency playback system by making the streaming buffers the same size as the audio file and pre-loading the buffers (which works fine) but I've hit a snag.
I've been trying to get the streaming to work at different sample rates so that I can play back the same sample at different pitches. I managed to do it by modifying the sample rate in the AudioStreamBasicDescription structure but in order to actually make the stream playback at the new rate it seems you have to create a new output, reload the audio file into the buffers and re-enqueue the output queue before starting playback again, otherwise the sample rate change has no effect.
There is a method to set queue properties; AudoQueueSetProperty() but unfortunately the sample rate Property (kAudioQueueDeviceProperty_SampleRate) is read-only
Can anyone suggest a way to achieve this with AudioQueue or do I need to move over to OpenAL?
Thanks,
Neil

Dan,
there is one point in your understanding, which i am not sure what you think about when talking about it: I understand E-series devices do not support this property change while the VI is running.
infact, you cannot change the sample clock rate during acquisition. but
this does not mean that you cannot change it while the VI is running.
you have only to interrupt the acquisition. since you want to acquire
continuous, this would have the same effect as stopping the vi, i asume.
so the best way to accomplish this task is to use an external clock.
this is e.g. often used for acquistion on rotating shafts. the
acquistionrate is always e.g. 24 points per revolution regardless of
the rotational speed of the shaft, except for a maximum frequency of
course.

The sample rate in my code is too low. Is there a way to make it run faster?

Dear Sir,
    I am a LabVIEW customer, and just have a question about LabVIEW.
    We are running a code of "Wirebonder Project", but find the sample rate is too low. I'm wondering if there is a way to make it run faster. (I have
attached the code here.)
   Thank you very much!
Yours Sincerely,

Hi Xian,
What system are you running this code on and are you using the LabVIEW Real-Time Module? There is a presentation online on Optimizing and Benchmarking Real-Time code with useful related links as well as other articles in the DevZone on things like Benchmarking an Application Using LabVIW Real-Time and DAQmx.
As you can see, this is not a simple question, so take a look at the information in these links and see if you can narrow down what in your code is running slowly and how much you might be able to improve the speed.

What are the Bit Rates of the Music Store and Podcasts?

What is the bit rate quality and format of a song downloaded in the Music Store? And podcasts? Are they perfect, Apple Lossless quality or what...?

This might be true, but you won't experience any improvement in sound quality. Here's some info on bit rates:
This was originally posted by the incredible Sparky the wUnderdog
"As a general principle, you can fit more CDs on your iPod if you encode at lower bitrates (making smaller files), but at the cost of audio quality. Lossless promises to capture all the data on the original CD (thus preserving quality) but coded so the file takes half the space. MP3 and AAC (an implementation of variable bit rate MP4) both eliminate some of the information on the CD in order to compress the digital recording into ever smaller files--the lower the bitrate, the smaller the file, but smaller files mean more information lost and consequent poorer sound quality.
iTunes's MP3 encoder is so-so; the LAME encoder is better at preserving sound fidelity to the original. AAC files ripped in iTunes certainly sound better than its MP3s, with audio quality close to the best LAME MP3s at higher bitrates. With the type of music I listen to most often, sound quality declines substantially as bitrates fall below 256kbps, but LAME or AAC @ 256kbps sounds pretty darned good, and at 320kbps LAME alt-preset-insane is amazingly faithful to the original. However many users claim that with the music they listen to they can't hear the difference between 192 or even 128 kbps files and the original CD source, so they naturally choose higher compression rates to fit more "songs" on their iPods.
CDs take approximately 10MB per minute of music; Apple lossless takes 5MB/minute; LAME insane takes 2.5MB/min; AAC or MP3 at 256kbps take 2MB/min; and iTunes Store files (AAC@128kbps) take 1MB/min. At these rates, a 20GB iPod (really 18.6GB) can hold anywhere from 30 hours to over 300 hours of music. (iPod marketers express this potential playback capacity as "songs," figuring 4 minutes per song--thus 300 hours at 128kbps = 4500 "songs.") You will need to listen to samples ripped with different bitrates and codecs to determine the optimum tradeoff point for you between quality & quantity. It's worth taking some time to do this at the start as it sure beats reripping everything in your collection 2 or 3 times to get it right later.
So far as convenience goes, nothing beats iTunes's one-step process. To change bitrate as you import from CD, go to the iTunes menu > Edit > Preferences, select the Importing tab, choose AAC or MP3 encoder in the "import using" selection box, then choose "Custom" in the "setting" box, and the window permitting bitrate selection will pop up. If you choose iTunes MP3 encoder, at least use VBR (variable bit rate) to maximize the sound quality. (VBR increases sample size as data complexity increases.)
If you would prefer LAME MP3s, fear not, for the easy-to-use CDex ripping software is a free download and requires only one simple extra step to get the files into iTunes for transfer to your iPod. Now if AAC sound quality is comparable to LAME MP3, you might wonder why you should even consider LAME: Because of portability to other devices. At present, hardly anything but iPods can read AACs or Apple Lossless, but almost everything reads MP3s. So if you plan to burn CDs of your compressed files for playback on your home or car CD player (for instance), it would be wise to choose MP3.
One other consideration specific to the iPod: It has a 32MB cache. If you choose a compression rate that results in large files (i.e. lossless), then the cache won't hold very much 'music' and the hard drive will have to spin up frequently to fill it, and that will shorten your battery life somewhat."

I have accidentally deleted my voice memo when i pressed the 'delete' button, thinking that is to change the name of my voice memo. is there a way to retrieve the memo back?

I have accidentally deleted my voice memo when i pressed the 'delete' button, thinking that is to change the name of my voice memo. is there a way to retrieve the memo back?
really do not understand why apple provides just one confusing delete button in its newer ios, instead of the previous versions which actually gives a confirmation button of whether to delete voice memo.

What system did the Mac come with and what system are you running now? If it's 2 years old, i.e. bought in 2010 then it came with Leaport or Snow Leopard installed and would have had install disks. Included in those disk would be a disk similar to one of these:
That would have included iPhoto 8 (09) if bought before October 20, 2010 or iPhoto 9 (11) if bought after that date. In either case you should have a disk like in the screenshot. If not then you'll have to purchase an iLIfe 11 boxed disk from a 3rd party retailer like Amazon.com: iLife 11 and install your missing applications from it and then apply the latest updaters from the Apple Downloads web page/

If your Lightroom 6 is crashing in the Slideshow module, check the SAMPLE RATE of your music track

After spending over 2 hours with an Adobe technician who had control over my Windows 7 machine, I've learned something that I don't think Adobe knows yet... I upgraded from LR 5.7 to LR 6 (not CC) and began having issues when I was working in the Slideshow module. When trying to add a music track, Lightroom would crash ("unexpectedly quit"). I couldn't for the life of me figure out why. I turned off the GPU since a fair amount of chatter on the forum related to that, but it didn't change anything.
So I finally waited patiently for the Adobe Chat line to finally get a tech to respond...and he was exceptionally detailed and methodical in his approach to diagnosing my issues. I could follow on my screen as he did a variety of things that indicated he understood what he was doing. Unfortunately he got to a point where he thought (as did I) that he had found the problem/solution...which he thought was related to the bit rate. He concluded that music with a Variable Bit Rate (VBR) as opposed to a Constant Bit Rate (CBR) was causing the problem. Also unfortunate was that this "discovery" was near the 2-1/2 hour mark and we did not apply the scientific method to property determine if we had narrowed down to cause/effect.
Based on my further analysis, he was close, but not right on. It isn't the BIT rate mode that is causing the crash, but rather the SAMPLE rate. Turns out that the vast majority of songs in my iTunes library have a sample rate of 44.100 kHz--and those work just fine. However, I have about 15 songs, mostly downloaded as free background music from the YouTube creation library, that have a sample rate of 48.000 kHz--every single one of those cause my LR6 to crash.
If you're having a problem with Lightroom crashing in the Slideshow module, check the SAMPLE RATE of your music track.

If you're on Windows, check out a free program called Audacity--it's fantastic. With Audacity the process of converting a 48.000 kHz to 44.100 kHz is as simply as opening, changing the sample rate, and then exporting again, as an MP3.

Is the sample rate half with the snd read waveform.vi?

Hi Guys,
I plan to use the PC soundcard for data acquiring with the standard LV "snd read waveform" vi. During programming I found that the sample rate is the half of the adjusted value. For example when I set
- the format to 8bit mono
- the buffer size to 11025 byte
- and the sample rate to 11025
then the operation takes 2000ms. I would expect 1sec.
Used system: LV7.0, WinXP SP2.
Does anybody know the reason? I have to use 44100Hz sample rate (44100 "individual" sample per secundum) in my application.
Thanks,
Tomi

To be more precise, that's the time take for the below mentioned finite cycle
SI config>> SI start>> SI read >> SI clear.
Its this 'entire' process which takes 1997 milli Sec
Now, what you really have to check is wheather your 'SI read' function is living up to the sampling rate you have set!
Check that by putting your 'time elapsed' check for SI Read function alone!
Hope this helps

Conflict between the saved data and the sampling rate and samples to read using PXI 6070e

Hello, I am using PXI 6070e to read an analog voltage. I was sampling at 6.6 MHz and the samples to read were 10. So, that means it should sample 10 points every 1.5 um. The x-axis of the graph on the control panel was showing ns and us scale, which I think because of the fast sampling and acquiring data. I use "write to measurement file" block to save the data. However, the data was saved every 0.4 second and as 35 points data at the beginning of each cycle (e.g. 35 points at 0.4 sec and 35 at 0.8 sec, and so on) and there was no data in between. Can anyone help me how there are 35 reading points every cycle? I could not find the relation between the sampling rate and samples to read, to 35 points every 0.4 second!
Another thing, do I need to add a filter after acquiring the data (after the DAQ assistant block)? Is there anti-aliasing filter is built in PXI 6070e?
Thanks for the help in advance,
Alaeddin

I'm not seeing anything that points to this issue. Your DAQ is set to continuous acquire. I'm not sure if this is really what you want because your DAQ buffer will keep overwriting. You probably just want to set to Read N Samples.
I'm not a fan of using the express VIs. And since you are writing to a TDMS file, I would use the Stream to TDMS option in DAQmx. If you use the LabVIEW Example Finder, search for "TDMS Log" for a list of some good examples.

What is the best audio or voice audio recording app for iPhone 5 because I want to record audio at a book signing event this coming Tuesday!!! Please get back to me as soon as you can! Thanks

Ok sorry to bug ya again but if I use the voice memos app if I have the screen locked and just on my belt clip on my side of my pants will it still pick up the authors voice and do I need to have all the volume turned all the way up for it or do I get the app u said for better sound?

CS6 will not accept my condensed mic stating; 'the sampole rates of the audio input and output do not match. Audio cannot be recorded until this is corrected. Use the appropriate operating system or audio device control panel to adjust the sample rates

!

The first things we need to know in order to be able to help are what are your operating system and audio device?

What is the Data Rate of the Cache in Adobe Premiere CS6

Hi,
Trying to build a raid array to edit with and want to know how much speed i need for caching read/write drive for premiere and After Effects. I'm of the impression that the cache doesn't need more than a single 7200rpm drive (~120MB/s) but really i have no clue what the data rate that adobe caches to is or what the data rate to read is
so it's 2 questions
how fast does premiere write the cache? (i know this is system dependent but a ballpark figure would be good for say a sandy bridge i5 2500k system with a 2 raid 7200rpm drive)
and
what's the data rate to read the cache in a 1080 24p file?
also, when doing the final export does premiere/after effects read from the Cache or the original files or both?
thx,

How can I change the sample rate (delta X)?

Hi, I create vi which can measure resistance, it will record the data and write to a file.
however, I want to change the sample rate which is delta x. is that anyway I can do?
I have try to put a clock inside the loop, it does slow down the speed but not the sampling rate.
Please help me!!
Thank you!

Hello Shan405,
Adjusting the Reading Rate of a DMM
As noted in the above DeveloperZone article, there are a lot of factors contributing to a reading rate of a DMM. 'Sampling rate' can only be configured in digitizer mode, which can only be achieved on the flex DMMs

Setting the sampling rate in SignalExpress

I am using a cDAQ-9172 with a strain gauge module and a thermocouple module and using SignalExpress. I want to acquire data at a pretty low frequency rate (2Hz), but I am unable to use 1 sample on demand in the acquisition setup. I get the following error.
Error -201087 occurred at DAQ Assistant
Possible Reason(s):
Measurements: Task contains physical channels on one or more devices that require you to specify the Sample Clock Rate.
Specify a Sample Clock Rate.
Device: cDAQ1
I am unable to setup a sample clock rate as it is 'blacked' out by the software in the 1 sample on demand mode.
When I try to use continuous or 'N' sample mode, the cDaq is sampling at a rate of around 1600 Hz, even though I am putting in a value of 1Hz on the seti[ screen. The large amount of data will prevent me from downloading the data to Excel for further reporting. I obviouisly don't need to sample my TC module at that rate either.
Is there anything I can 'easily' do to decrease the sampling rate down to a low level? Everything I have tried doesn't seem to work and I don't really want to go away from SignalExpress.
Jay

Hi Jay
I am assuming that you are using the NI-9237. This strain module has only a specific set of sampling rates. If you specify a rate that is not supported it will corers the rate to the next higher sampling rate. Also since you are using the cDAQ chassis, there is only sample clock so it must choose the highest sampling rate. So it is not possible to sample at a lower rate. Please see the following link.
If you have access to LabVIEW then I would suggest taking your readings at the fast rate and then average the samples before you write them to your file. The following link has some more information on this.
If you are limited to Signal Express, this task is tricky. If you select a N-Sample acquisition, set the samples to read to greater than two, and set the post acquisition delay under the execution control tab to 1000, you acquisition will acquire the two samples at the very fast rate, but it will wait 1000mS between each acquisition. This will slow the overall sample rate.
