Please recommend a voice recorder under 350. If you do so, you can add 30 points

Nowadays, many mobile phones can be equipped with recording software. It has file format optional, *** compression rate optional (to determine file size and sound quality), AGC dynamic volume compression, voice-activated automatic recording (to avoid recording without content) and the valve control value is infinitely adjustable. The function, convenience, and effect are even far more than the average voice recorder, and you can put as big a card as you like.

With Bluetooth headset, it can achieve wireless recording of about 10 meters. With FM microphone, it can realize about 50 meters of recording (the mobile phone must have FM and FM internal recording function).

If the environment is noisy, a directional microphone must be used. You can also make your own. Lead the microphone out with a cable and install it at the bottom of a paper tube, and stuff some sponges in front of the microphone and in front of the paper tube, otherwise there will be a resonance.

The longer the paper tube, the smaller the mouth, the stronger the directionality, the smaller the recording angle, and the better the anti-environmental noise effect.

Finger-sized Bluetooth headphones are stuffed inside a rag doll and glued to the podium, and people think you're a welcome doll.

I use the Miura V21 I think the sound quality is okay, the sound quality is large, the recording effect is OK, put it at a long distance, the voice of the voice can be recorded, but with the kind of No. 7 battery that can be removed. The new section you talked aboutV18,I bought a voice recorder and watched it at the time,It's **expensive,And the sound is not as big as MiuraV21。

I suggest you go and see the Patriot, I use it now, it feels good, in fact, this thing has started, how to use it and how to use it. Go see the Patriot under 350! @

The domestic ones are all right, but the sound quality of the domestic ** is about 200, and the sound quality is very good, if you get on the 300 domestic recorder, it is very powerful.

Time, as a student, is a fixed amount of time that you record every day, so it's not the most important consideration.

The battery must not be selected, and the longer the standby time, the better.

The recording distance must be taken into account, and I don't know if I can put a voice recorder on the teacher's podium now......

The storage method, the external one is more convenient than the built-in one, but it is not necessary, and the product of about 100 yuan may not have an external SD card.

Compared with the fourth article above, the best focus is on sound quality, and professional digital voice recorders and professional voice recorders are completely different concepts.

If all these things have been considered, then in fact, the multi-quality option, with noise cancellation, quality assurance products are the best.

For example, Hyundai E60 this, 98 yuan.

Capacity 8G, LP HP dual mode dual varied recording, up to 576 hours of storage, up to 10 meters away, but also with noise cancellation, microphone.

As far as students are concerned, this is enough.

So, when you don't have to worry about buying a fake, just pay attention to the warranty period and the replacement return guarantee.

For this reason, I don't recommend **, unless it's the same city.

1) I just bought a set recently: I bought a Lenovo B520 (280 yuan to hand including shipping), and a stereo microphone with Audio-Technica (78 yuan including shipping).

2) The domestic keys are not very sensitive, if you want to record with good sound quality, you have to tune to the highest quality recording mode, generally 1GB can record for 17 hours, *** format, sampling rate 128kbps. Many voice recorders can achieve this length of time and sample rate. However, there are two major drawbacks to the built-in or external microphones they come with

One is that the noise is loud, the current is loud, and the second is that the sensitivity is not enough!

So I have an original Audio-Technica microphone, and of course you can also buy a Sanyo HM-200 (130 pieces each). Audio-Technica AT9830 This stock microphone I think is very cost-effective, the recording noise is very low, and the sensitivity is high!

3) The voice recorder suggests that you save a little and spend more than 100 yuan to buy one that can support external microphones. As long as it supports 128kbps sample rate, it's fine. In addition, it is best to use dry batteries, because lithium batteries are easy to break, and if they are used for a short time, the battery will be completely scrapped after a long time!

Isn't it wasted?

4*) I bought this set of things, I feel that the effect is good, except that the screen of Lenovo is too small, and the old cold light looks uncomfortable, and the recording is super clear after the microphone of the Japanese Audio-Technica, and it sucks with the original microphone!

I mainly suggest you: the voice recorder can be bought with a poor one, but if you have to match it with another "golden ear", the effect will be ox X!

And you can save money!

I bought a Miura V21 that was good.

It is very good to use, the recording is clear, the sound is very loud, and the distance can be recorded clearly.

I also use it in the classroom.

Newman's RV12 2G 299 has a recording time of 548 hours, and you can check it out online

I bought the Suozhi voice recorder R-05 and the effect is good, **It is also suitable Small and simple.

If the voice recorder requires a camera and can take pictures, and it needs to be like a pen, and the battery is durable, and the recording time should be up to 10 hours, you will not find what you need in the market.

If you cancel the video recording and photo function, then you can buy a professional voice recorder to meet your needs.

If it is used by students, used in the classroom, the area is wide, the distance is long, the recording effect is required to be clear, and the battery is durable, then you need to make some adjustments, and the well-known brand of voice recorders of about 200 yuan can meet your needs, such as Xinke V20, Xinke V18, Miura V21, Yajia AKAI A06, Yajia AKAI A09, A10 These cost performance is good.

But within 100 yuan, you can consider the new branch V09 U disk type voice recorder,There is no display screen、Xinke V06 like a pen voice recorder,But ** is also higher。 But these two models have no advantages in long-distance recording and recording time.

It's up to you to make your choices, but hopefully you'll get the best value for your money.

Jinghua Digital's voice recorder is good.

The few I've used are

**Ranging from 100-400-600. Two or three hundred is very good, free repair and maintenance throughout the country

The recording time is very long.

The quality of recording is greatly affected by the distance and the environment, the current popular voice recorder recording distance is about 15 meters, if you want a longer distance, then it is recommended that you use a voice recorder with a wireless microphone, half of which can be increased to about 30 meters.

The relationship between recording quality and distance is that the closer the distance, the better the quality.

The relationship between recording quality and environment: Usually we record directly with the built-in microphone, and sometimes the environment does not allow the recorder to be close to the speaker, so it is required to have a relatively quiet environment near the recorder, otherwise the noise generated nearby is easy to be recorded and become a source of interference.

Of course, there are many factors that measure the quality of a voice recorder.

For example, the voice recorder adopts automatic gain control AGC, (automatically adjusts the strength of the amplified signal as needed) intelligent voice-activated recording, space-saving, recording monitoring, and repeating functions.

And so on foreign big brands will also be sony.

Quite practical audio and video recorders, let's make up a number together, and I can't buy it if the number of people is not in a group. . . Let's make up the numbers if you need them. The address of the pen ** is to take someone out to talk about things or buy things, so you are not afraid of being squeezed, because you can secretly record the video and have evidence. Hehe.
