Record Streaming Audio

Anyone know how to record streaming audio.... like...I'm streaming radio off the net...and I want to record it thx

Well not that this is a lot of help, but you can record using the Note recorder or (my suggestion) using Sound Explorer which is a great MP3 recording device. This is in the case that you at least want to make notes of what you are hearing. If your in a quiet room the sound will record pretty well just by picking up what your radio is transmitting...
another likely theory to work (still have to do this myself) is to actually make a wire that plugs into the headphone jack and redirects the audio to come straight from the headphones into the mic. As for a software solution, there are none for the PPC that I know of. There are some for the PC, but thats not what your looking for.

Record uplink/downlink speech streams? (WaveIn, TAPI, RIL?)

Hi,
I'm trying to record both uplink and downlink speech streams of my XDA II during a phone call.
I tried many different things but couldn't get working any of them:
- I first tried the waveIn/waveOut API and thought, in the first place, that I was able to record the incoming and outgoing audio streams, mixed together. But I quickly realise that what I was recording was only the sound from the mike, and that the speech of the downlink speech was going from the speaker through the air to the mike. So I was recording my own voice (from the mike) and the voice of the other part (from the mike too as the sound was going from the speaker to the mike).
- Then I had a look to the TAPI API. I was able to answer calls but it was impossible for me to access to any of the audio streams. I think it's a limitation of the device, and that the TAPI API hasn't been fully implemented on the XDA2. But I can't be sure of that.
- Now I'm trying to use RIL, which seems to be a layer below the other APIs. I believe it might be possible to access to the audio streams, but I have no idea how.
- I also think that the audio data of both streams must be stored in the memory, somewhere in the device. But where?
Any ideas or suggestions on this? Do you think I should keep investigating RIL?
Thanks a lot
Ben

There is 3rd party software that will do this.

Re: Record uplink/downlink speech streams? (WaveIn, TAPI, RI
there is no such a program. The only thing yor program can record is the sound from microphone. This can be tested by connecting a headset to the device and trying to record anything during call. Only ugly devices like Anextek SP230 can record both sides because microphone is wired to the speaker.
You cannot use RIL or TAPI to record calls. It is a limitation of both hardware and OS. Maybe WM2005 would support this.

Yes I don't thinck there is such a program (I've been looking for such a program for the past 2 weeks). All recording softwares you can find don't do much more than using the waveIn/waveOut API and so they record only the sound from the microphone.
Mamaich: Would the Anextek SP230 allow me to record properly both sides even if I use a headset while recording? How come the microphone is wired to the speaker? Does that mean that the sound going to the speaker goes also to the microphone? Wouldn't that introduce a lot of echo in the network during phone calls?
Even if we are limited by the OS there must be a way of getting the speech, because somehow the audio data must be stored somewhere in the device (either the GSM memory or the device memory). And that's what I would like to find out.
Thanks.

Yes. I owned Rover S1 which is based on Anextek and checked this.

There is no echo during phone calls, but when using VoIP and similar programs the echo is terrible.

Call is processed by the GSM module that has its own CPU (some sort of ARM with DSP extensions). You may reverse engeneer its firmware, but it is very complex. On XDAs its OS is based on "Nucleus PLUS - Version 1.0.G1.1" by ATI. In Anextek it is Siemens MC45 module.

Well all the people that claim that Vito sound software and others record both sides of conversation on the forum are lying?
Also it seems this article must be untrue
http://asia.internet.com/news/article.php/1383691
It says that 2 way recording is possible on the xda.
excerpt: Designed for busy people on the move, the device combines a color personal digital assistant (PDA) and General Packet Radio Services (GPRS) handset into one compact unit. Among the things that the users are able to do with the unit include recording a two-way phone conversation or a 'live' conversation, listening to music, watching video clips and reading e-books.
I have now tried vito sound recorder 2005 and it doesnt allow both sides of conversation to be recorded on my xda, I took a look around and it seems the old siemens sx45 had the capability with its recorder software, here is an excerpt.
The sound recorder lets you record from the built in microphone or for ultimate fun, both sides of a phone conversation, which can be played back whilst in conversation. Confuses the hell out of folks when they hear what they’ve just said.

In a sens they are not really lying because you can record both sides of conversation, if you allow the sound from the speaker to go to the microphone. If you don't use a headset and the volume of your speaker is high enough, that will be the case. The voice of the other part will go through the air before being recorded. That's why people claim that you can record both sides of conversation even though the quality of your recording is rubbish.

With vito you get perfect reproduction of the caller but zero from yourself.

AD2P Audio

Any of you using the Desire HD with a BT Stereo Radio and/or stereo headset. The sound quality sounds really bad to me. I had the same thing on my HD2 @ default settings, but fixed that by changing the linespeed in registry. (bitpool on older WM phones)
Have been googling and can't find anything of the sort for Android. Is there a way to fix the audio quality?
My brother has the SE Xperia X10 and it has way better AD2P audio quality, even though it's still android 1.6. So it's not an Android bug, but rather a driver/setting somewhere.
Also the range the BT has is really small, I have a Logitech Pure-Fi Mobile speaker, which connects through BT AD2P, the quality is lower then on my HD2 (after tweaking) and the range is only 5-7m, while the HD2 managed to have skipless playback and higher quality at over 15-20m...
Apart from this I'm really loving the phone . And my car radio has full support for the other BT features. Like skipping tracks (in Spotify) and dialing numbers via the address book on my car radio instead of on my phone. And see who's calling on my radio's display.

Hi there, I'm really interested in that too. Would you say it's just a slight problem of the sound quality or is it merely unusable?

If you use Bluetooth headset you can forgive about good music quality. that's all
if you need good quality audio in bluetooth, buy this:

You can compare the quality with 96Kbps MP3 which is really bad imho, but still usable. It's about the same on many phones though, allmost all are set to max 31 bitpool... But with windows mobile it was an easy fix.

As the source code is out, I hope the ROM builders can soon find a way to fix this.

Hi
I use a pair of plantronics 590e headphones over A2DP and the quality is brilliant! I have not changed a thing in the setup.
I wont play anything lower than 192kbs (most of my mp3 are 320kps) as i am a real fussy git when i comes to audio.
I have used the standard music player and tunewiki and both are perfect!
Are you atchaly using the A2DP or standard mic and mono sound protcal for calls?

My MM200 Sennheiser work flawless. Music is rich and crisp!

You won't know the difference if you haven't heard the difference between bitpool 31 and bitpool 58, it's like night and day to me. Even 256kbps MP3 sounds bad to me tho.
Tried different audio files and it's not spotify causing it. As my brother is also plaything through spotify at HQ settings (which is 160Kbps OGG, comparable with 320+ Kbps MP3) ...
Eagerly waiting for an AD2P fix for android.

When I have my HD playing music through my Car's Bluetooth the quality is also pretty poor.
For some reason I can't choose any of the EQ settings? If I could just try and add some treble I think I could put up with it!

Just tried playing music via bluetooth to my sony head unit in the car and it became so choppy it was painful to even try to listen to it.
Great phone but really disappointed that there is a problem like this as one of the main uses of my phone is for audio in the car.

I use a Sony Ericsson mw600 and the quality is not good. The same headset with my sisters itouch and it sounds great. Is this a hardware or a software issue?

You must be careful with the mw600 that it connects in the correct mode. As headphones NOT headset for music. If you get it wrong it will sound awful. You can check by tapping the Mic during playback, if you can hear it through the headphones you have it set up wrong

i had exact earphone, but it's just awful. first of all; htc doesn't make me choose any sound enhancements, other thing is, my 320kbps musics aren't different from 96 at all.
ps. i am an audiophile.

Imanaged to find my old iTech BlueBand headset yesterday and gave that a go. Sound quality was loud and clear and well balanced.
Shame about the delay though - it's worse than I'm used to. Video is pointless as the lag on the audio is far too much to be bearable.

Acer A500: Microphone, Skype, Gtalk

Using Skype, Gtalk, etc with A500.
I tried to make a call with Skype (Skype testing service) - the sound quality was poor.
Tried to make a call to another Skype user - I could hear him well, but my voice was muffled.
Solution:
Just plug in a headphone/earpiece (that has NO microphone) into the headset. You can then use the internal mic on the A500 to make your calls over Skype. The sound quality is very good in both skype and gtalk.
I did try my Iphone's earpiece, which has a mic, but the sound was muffled.
Hope this helps.

I have to do this too, do any others not have to do this?

I spoke with my wife a few minutes ago and asked her how I sounded the other day. I used Gtalk and she did too... she was able to hear me and I was very clear.
Not only that, but I was using 3G with only a single bar. Had poor video quality obviously, but sound was flawless.

Called with video on gTalk, being on WIFI - good quality audio, average video...
Skype working with no problem, too

Uhh gtalk has video with gmail gtalk or other supporting android device.
Skype I think has video only with select Verizon handsets or something like that

Only GTalk had video calling feature for me. It just was here originally. Called from my Desktop with web-cam to my Acer.
Skype - audio only. No video. (yet? )

ok got you. thanks guys

how did you guys managed to use gtalk with video in canada? Isn't it only available in states ?

Nope It is available everywhere in the world.
If the person you are trying to reach has a video version of gtalk you should see a green camera on the side.
PS for those that do not have a video version of gtalk on their android phone you can use a free app called vtok which allows videoconferencing with gtalk client
That is what i have been using on my HTC DHD and it works great.

Where is the microphone located ? I'm never sure which areas to aim my voice towards when speaking.

Holding the A500 in portrait mode, with the volume control button on the right, look for a small hole on the right side, between the glass and the bezel.
It is about 5 inches from where the power switch is located.

If you have the Acer case, the mic is cover by the velcro tab (go figure).
Is there a mic for the front camera?
I can't seem to find one.

Thank you. Took me a minute but I found it. Voice to text has been very difficult thus far in comparison to my nexus 1.

is there a software fix to the mic issue?

thanks so just download the skype and you are in business. Is this easy to use sir?

found a fix, you can use an external mic the one built in is good but the software is making it retard. If you plug in a headphone with a mic in it or just a plain old mic it will work great, i have tested it for a good 3 hours, it works. Much much better sound.
google voice search doesn't work for $$$$ no matter how good your mic is. 3.1 was a huge ****up by acer HUGE

Can someone do some modification so that we can use video as people in galaxy s did?

my mcs are worthless can't do anything with them no voice commands work neither will the search or Skype or GT. Absolute bs

My mic works flawlessy for google voice search i have no idea how?

I think the issue is that some folks aren't used to a true noise cancelling mic. It's using a dual analog noise cancelling mic. so it's filtering noise while capturing your voice or capturing your voice 'twice' if you're using it properly/close by.
If you're trying to use the Mic in a noisy area, it may cancel some of your voice as noise unless you speak up or put it somewhat close to your face or speak directly facing it. In other words, picture yourself on a video call. When you set yourself up to be seen by the camera properly, that is ultimately when the Mic will be at it's best.
I imagine people are using it with with a phone's mic in mind but they are unfortunately not the same. A phone's mic is located as close to the mouth as possible without allowing users to blow into it. The mic on the A500 is located away/out of finger reach, primarily and directly facing your mouth.
In the end, I think the best advice for using the mic is telling you to use it like you're on a speakerphone call. Clear, precise vocalization. You can also run the best test with the Voice Recorder to kind of hear how well your voice is picked up from various angles. I found, as I mentioned before...that I am most clear in either portrait or landscape mode with the tablet roughly a foot to 18 inches from my face, similar to how I'd hold it for a web cam. I found that if I spoke as if I were using a speakerphone, I got the best results....even while the TV is on or music is playing. I lost ground however, when I lay the tablet flat on a surface or docked out of line of sight, that is, beside me or elsewhere. I also have no issues with using Google Voice Search.

External *stereo* microphone for both video and audio only recording?

Does anyone have any experience in regard to connecting external microphones to the OP5?
The idea behind this is that I want to record classical music with a high dynamic range without any compression or clippings. I'd like to record myself playing the piano both with an HD video and good audio quality or just use it as an audio-only recording device for concerts etc. In the end I'd like to have a recording that gives me at least uncompressed PCM-audio at 16Bit and 44.1kHz as CD quality stereo tracks.
The microphones in question could either be small binaural microphones or a semi-professional setup with a pair of Neumann U67/87 and I'd like to know whether the OP5 can make native use of those microphones, i.e. using its own Analog-to-Digital converter, or whether it is necessary to directly feed a pre-processed digital signal to the phone via USB.
Any pointers to an existing discussion are welcome, just as much as your personal experience, tips and tricks for this kind of set up.

Hi, I have been looking and looking, and it seems that the default camera app doesn't support external mics, but a 3rd party app does, like open camera, but for me, it zooms in a lot when recording.... it sucks

I can now state that it is possible to use external microphones.
I've bought a microphone pre-amp UR22-MK2 by Behringer that puts out a digital signal via USB an using a USB-To-GO adapter, I can feed this into the OP5. The stock camera automatically detects this external audio source and uses it, deactivating the internal microphones.
Unfortunately there are sometimes audible clicks, which do not occur when I record on a PC from the Behringer input. I suspect it's small hickups due to compressing the audio track while recording into an MP4 container.
I wish there was a video app that lets me define lossless audio recording.
