オーディオに拘る方、少しでも良い音のために、機材、視聴環境を調整
したい方のために制作した、世界で唯一の耳のトレーニング音源です。
全90曲目のWavファイルです。USBメモリ付きです。

例えば、ステレオ再生時、左右の音に

・遅延が発生したら、どんな音になるか?
・位相差(反転)が生じたら、どんな音になるか?
・音圧差が生じたら、どんな音になるか?
・周波数でどのような違いが生じるか?

等、疑問に思われた方は多いかと思います。

これらの現象は、日常のオーディオ機器では当たり前のように生じていますが、
”その原因を特定するための、耳のトレーニング”が出来ていないため、
改善できず、問題のある視聴環境を強いられている人が多数いらっしゃいます。

そこで、それらの音の違いを学習できるよう、周波数50kHz~8000kHzまでの各種
ステレオテスト音源(全90曲)を制作致しました。
できるだけ理想的な環境でお聞きになることで、音の違いを理解・学習することが
可能になります。

オーディオ機器の改善(調整)、聴覚の強化に大いに役立つ、世界で唯一の
オリジナル商品です。

※別途、オーディオ調整用音源Wavファイルも出品しております。
こちらとセットでお使いいただくことで、オーディオ機器の調整能力が
最大限高まります。オススメです。
セットの場合、合計1000円割引させていただきます。

※製作に当たっては、業務用の波形製作ソフトと専用スタジオ
における検証テストを行っております。

※本製品は著作物ですので、配布は禁止です。
シリアル管理を行っておりますのでご注意下さい。

※多くの環境で再生できるよう、CDと同じ、44.1kHz、16BitのWavで制作しております。
万一、再生できない場合は、返金致しますので、その際は連絡をお願い致します。

発送は、クリックポスト(164円)を予定しております。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao-holdings.com and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
